The Diamond features a 3.2 megapixel main camera with autofocus, which appears to be the same as the original.  It performed well, with good color representation and crisp lines.  There was a bit of blurring at times, but it’s very possible that can be chalked up to shaky hands as other pictures turned out clear.

The autofocus is triggered by bringing your finger near the d-pad center button; the camera will focus and pressing the button snaps the shot.  There are 5 resolution steps, a two and ten second self timer and the user can choose from predefined white balance settings and adjust the brightness.  The camera can shoot with grayscale, sepia or negative effects and there are user preference options such as where to save the files, review duration, etc.

One cool new feature is panoramic mode, which allows the user to snap sequential pictures and stitch them together giving the effect of a wide-angle lens.  It is achieved by taking the first shot, then lining up cues of a ghost of that image on the screen with the new image being taken.  Three shots in all are taken, leaving the picture with an overall resolution of 1408x480.  Results weren’t perfect, but we were impressed by what we were able to achieve.

Videos can be record in MPEG4 or H.263 formats and can be shot in Small, Medium or CIF (352x288) resolutions.  The camcorder utilizes the autofocus features as well, but as expected the overall quality was not on par with the camera.  For a cell phone it was above average, there was some pixilation which got worse as you pan around, but it was plenty good for YouTube and general web use.  The user can again change white balance settings, adjust the brightness, change the effect and set a few preferences, but overall the settings are minimal.


HTC offers a custom music player and album viewer that is integrated within TF3D, but when media files are opened through the File Explorer Microsoft Picture Viewer and Windows Media Player serve as the default players.  HTC Album (the picture/video player) is very good, but the music player has some shortcomings.

HTC Album allows users to view pictures and video full screen.  Turn the Diamond on its side and the picture follows suit- gone is drawing stupid circles to get the picture to rotate!- and you can scroll through your media with the flick of your thumb.  The video player is very similar to the iPhone.  Videos play in full-screen landscape mode and tapping the video brings up transparent controls.  Even YouTube videos look amazing on the crisp, VGA screen.

The music player looks nice enough, but isn’t the simplest program to use.  From the Music tab on the homescreen you can control your music.  The interface is still a bit awkward, though HTC has made some improvements.   In the past art for each track was queued behind the playing track, but if it was from the same album obviously it would be the same art.  Now only different art is queued, but it’s more confusing than it should be.  For example, if there are four songs from Sgt. Pepper’s followed by two tracks from Abbey Road followed by a track from Revolver the user will see one instance of art from Sgt. Pepper’s, one from Abbey Road and one from Revolver, but when playing the first Sgt. Pepper’s track the same art will be displayed for the next three songs, with no indication that there are three other songs before you get to Abbey Road.  In our opinion HTC needs to just ditch this queued wannabe Cover Flow altogether and just display larger art of the current track.

The library works like TF3D, with tabs along the bottom.  In the library you can sort by artist, album, song, genre and composer.  You can create playlists, but otherwise you can either play all the songs at once or a single album at a time.  When you play all songs they are sorted alphabetically regardless of album.  We prefer Windows Media Player and its library, which allow you to play all albums in alphabetical order while staying true to the original track lists.

The MP3, AAC, AAC+, WMA, WAV, and AMR-NB audio codecs are supported.  There is no 3.5mm jack so the user is restricted to miniUSB headphones, a set of which is included in the package.  The quality isn’t bad, on par with included iPod headphones, but they will most likely be uncomfortable to those with medium and smaller ears.  There is a miniUSB to 3.5mm adapter, but we’re not a fan of adapters and their added bulk.

One very nice feature of the Diamond is the YouTube player.  It is a stand-alone program nearly identical to the one found on the iPhone.  There are four tabs: All Videos, Bookmarks, History and Search.  All Videos is further broken down into Most Viewed, Top Rated and Featured.  Videos launch in full-screen mode, and like the iPhone tapping the screen brings up transparent controls.  The scroll wheel around the d-pad is active here as well, though it’s not as smooth as we’d like.  The video quality was surprisingly excellent; videos looked superb on the VGA screen and audio was good and in-sync.

Teeter is maybe our favorite feature of the phone, and really shows off the accelerometer.  It is a Labyrinth-style game, where you have a ball that you need to tilt through a maze and avoid the holes to get to the end.  Not only is it a fun game, but it really showcases the phones abilities.  For instance, when you hit a wall there is a dull thud you feel that truly seems as if you’re hitting the wall with a metal ball.  We imagine it’s done though haptic feedback, but it sure feels like a solid thump and not a vibration.  (Yes we are aware there is a version of this for Jailbroken iPhones, but Teeter is better. ) Eventually you begin to play not on a flat surface, but on a 3D rendering of the original Diamond’s faceted battery cover!


The CDMA Diamond has 256MB ROM and bumps up to 288MB DDR SDRAM, with 4GB of internal storage in lieu of a microSD slot.  Windows outside of TF3D actually seems to run smoother this time around.  Out of the box memory usage was as high as 65% with the GSM version, but our CDMA unit is only using 35% of system resources which would explain the increased overall performance.  We hoped that HTC would address this issue, and it appears that they did.

Preloaded programs include Adobe Reader, Sprint’s Instant Messaging and the Office Mobile suite, among others.  There are loads of programs available for Windows Mobile, though many of them will not work with the Diamond due to its VGA display.  It is usually a simple fix by the writer, but lots of programs (such as the aforementioned and beloved One Touch Organizer) are not supported anymore.  The Diamond is not the first WM VGA device however, and as VGA becomes increasingly popular you will see more and more programs pop up.   No Java emulator is included, but of course users can load a third-party offering.

The Diamond features GPS, and Sprint Navigation is bundled and included with the required data plan.  It’s the best GPS program of the carrier offerings, along with AT&T as both are just rebranded Telenav.  Unfortunately the graphics are from a QVGA display, so they look a bit pixilated on the VGA screen, but it’s not as bad as it sounds and hopefully Sprint will update it soon.  The GPS on the Sprint version is unlocked (we’d expect the Verizon version to be locked down upon release) which means that programs like Live Search, Google Maps and other third party offerings are able to access  it as well.

Hi, great review and lots of details which is what I'm looking for. however, I would like to see how Sprint TV fares in this device compared to Instinct; as well as handwriting capabilities (as text input)... is it accurate with the stylus or finger? pls pls pls, any information is greatly appreciated.

2. unregistered

we have rev a coverage in our call center and the sprint tv quality is outstanding, way better than the instinct.

3. unregistered

wow, with this phone I almost have to say that there was no point for the instinct, besides to rival the iPhone in time, if they made a dumbphone version of this they'd be perfect

Will this phone come in black as well? It seemed there were rumors that it would launch in red but have a black back later. Any info would be appreciated. As for right now, I will have to see a red one in person to see how it looks as every review states that the red looks better in person. Also, any issues with overheating? Thank you for such a great interview.

fabulous review. i had this phone since telesales started to sell it. it is marvelous. the best phone period.

6. Paul unregistered

I've seen other reviews mentioned about the overheating/phone get hot problem... have anyone experience that?

8. unregistered

the battery does tend to get warm pretty quick making the back of the phone a lil toasty.

22. unregistered

I've also had the phones since telesales started selling it and I love this phone. In regardless to the saying of the battery over heating. I did alot of researching and tested the theory myself, it's not the battery that's over heating or getting hot. It's the radio that located below the battery area that gets heated, due to the manufactory squeezing it in a small area. To test that theory, when your phone heats up, just remove the backing of the phone and touch the battery, you'll find that the heat isn't there but below/bottom of the phone that gets hot. Thus far, no sulution to this issue.

I want to know if this phone will work on the GSM 800/1900Mhz Frequencies? According to HTC's webpage for this phone it is Dual-band (800/1900Mhz), CDMA2000 1xEVDO Rev. A/1xRTT and IS-95A/B voice or data with up to 1.8 Mbps up-link and 3.1 Mbps down-link. Trouble is I dont want to spend all the money then not be able to use it in the UK...

9. unregistered

this is the cdma version, you want the gsm unit which they also reviewed a few months back.

13. Pihrana unregistered

I only have 2 or 3 carriers that work in my local town. Alltel, Sprint/Nextel and Centennial....... I'll be going to the UK 3 or 4 times a year and want the phone to work while I'm their..... I know the UK has carriers using GSM 800/1900Mhz Frequencies, so are you saying that the Specification on HTC website where it states (800/1900Mhz) is not GSM? If not then what are they? Thanks in advance.... Want to get it cleared up soon so I can order something.....

14. David the Gom unregistered

dual band for this phone is 800/1900 Mhz CDMA, it's same "frequency" as 800/1900 Mhz GSM, but different "signal"...

16. Pihrana_Work unregistered

Thanks David........ You've finally put the nail in the coffin (which I am grateful for, because I havent spent any money)...... So... I'm still looking for a decent phone that will work in the UK and my home in the US. Any suggestions..? Please dont say Blackberry :)

with sprint the blackberry 8830 is your only option if you want to keep the same number. centennial is gsm like the uk, but theyre a small regional carrier and im not sure if their phones are unlocked. i dont know much about them, but you should be able to buy any unlocked quadband gsm phones which you can use both here and there. if you dont care about keeping your number over there (which youll pay a pretty penny for) you could also buy a cheap unlocked gsm phone and a prepaid sim for when you travel to the uk, and get sprint here.

21. unregistered

The Samsung Ace is a really nice phone that would work for you and is still windows mobile. But you lose the touch screen feature which is a turn off for a lot of people. It is a quad band phone though so it will work internationally...if you can afford to use the phone internationally

Keeping the same number while overseas is way over-rated as roaming charges are truly outrageous. simply get a cheap unlocked phone and buy pre-paid GSM sims wherever you travel..

By far this is a great phone I bought it the second it went on sale on sprint's website i have to say using this phone so far is wonderful i havent had any problems for example with the gsm version HTC has put a great effort into this phone two thumbs up for them. Furthermore i would like to get a black battery cover ..... but other than that its a marvellous touch screen phone i must also commend this review it was really detailed .....

18. deejal01 unregistered

i disagree. I had this phone for a bit and ended up returning it. I hated the phone because text messaging was a pain. HOWEVER, the one thing that I did like was the transcriber text entry. You could print or write in cursive or a combination of both, using the stylus, and it got it right almost 99% of the time. With some tweaking, eventually, it was correct 99.9% of the time. I miss that feature. Sprint needs a new line of phones and their current line up looks pretty bad.

Hello, I have seen comments on some sites that the app download can only go to ROM, and not the on-board 4GB RAM, is that true? Has anyone tried this out? any feedback is appreciated.

20. martin unregistered

I have downloaded tons of apps and it lets you choose where to put it. I have heard some users losing their internal 4GB Drive when playing around with hard resets, but then being able to get them back. This might be why they are commenting they couldn't put apps on the RAM.
