Big Mistake
Phone owned for - more than a year

This phone was great the first week, but can not handle heavy volumes of text and emails. I've replaced the "Jack" three times with my insurance and I only have one month left on my contract before I can replace it. I highly recommend "not" getting this phone. It was clunky, didn't do the job I was told it would do, and the coverage was spotty. The OS system would be great if the phone would have supported it.

Jack Squat
Phone owned for -

Looking for a new corporate phone to replace our aging fleet of phones, including my old school HTC 8525, I picked up the new Jack.
The key pad appeared easier to use than the old Black Jack 2's that we have running around the office, but this proved not to be the case. The stiffness in the keys, and the close proximity to each other led to many mistakes.
Samsung still has not quite figured out how to install a usable browser, and the touch screen was still hard to see in the sunlight similar to the previous versions.
Navigating the phone and using the menus was not as intuitive as you would expect from a manufacturer that has been doing this awhile. Why would you release a phone targeting a corporate marketplace with the "personal assistant" concept that doesn't even use Windows Mobile Pro? I need an assistant to keep track of information, not have it locked away in some sort of non-navigatable device that won't let me sort my emails or pop in and out of folders in Outlook.
Piece of junk was returned in 2 days and I have gone back to my old 8525, which may be slow and showing signs of age, but does what I need and how I tell it to.
The call quality was nice, and if you just want to have a cool looking phone sponsored by Ozzy, then this would be a good pick. If you are a business type, who lives on email via an exchange server, keep looking.
