What's rooting and what do I need to know about it?
Hi, Viswanath! Congratulations for getting the Galaxy S II, great choice! Basically, rooting an Android phone allows you to have administrative access to everything in it. When you root an Android phone, you get access to system files and all kinds of permissions. The most valuable thing to rooting a phone is the ability to install custom ROMs like CyanogenMod. If you really want to install a custom ROM on your Galaxy S II, we can recommend the CyanogenMod ROM, but keep in mind this will void your warranty. Here's a very detailed guide explaining everything you need to know about rooting and installing CyanogenMod on your AT&T Galaxy S II. It'll also point you to what actions you need to undertake in order to back up all of your information safely. In any case, we'd advise you to be very careful when attempting to root or install a new ROM on your phone, especially when you aren't completely sure about what you're doing.
Should I get the iPhone 4S or Galaxy Nexus, or wait for the Galaxy S III or iPhone 5?
Hi, Jagdeep! It really depends on how badly you need a new smartphone. If you're fine with your current one and can wait, it's always a good idea to wait for the new models to come out. However, if waiting is not an option, we think it's perfectly OK if you purchase any of the handsets you've mentioned. The iPhone 4S and Galaxy Nexus, or even the Galaxy S II are still very powerful and adequate offerings that will get every job done with ease. Now, which platform to choose between iOS and Android is up to your preferences and taste. But here is a comparison article that might make your decision easier: iPhone 4S vs Galaxy Nexus.
Carrier-unlocked vs Factory-unlocked
Hey, Steve! Whether and when you'll get a software update for your phone depends on a number of factors, not just whether your handset is carrier-unlocked or neverlocked (factory-unlocked). There really isn't a rule for that. With some devices, getting the update with a factory-unlocked handset might be faster than with a carrier-unlocked, but the opposite isn't out of the question as well. In most cases, however, you should have the ability to update your device if it's factory-unlocked, because the "carrier factor" will not be involved then. Updates should come automatically, but it's not 100% guaranteed. Plus, you might be able to get the new software faster if you attempt to manually search for and install the update.
Is it OK to buy a dual-core tablet, or should I aim for a quad-core one?
Hi, Tevin! Unfortunately, you didn't tell us how much money you've prepared for a new tablet purchase, so we can't recommend the best one your money. But, the good news is that we think a current/last-gen tablet will be perfectly suitable for you. There won't be so much of a real-world benefit from a quad-core tablet for at least another year. That said, it's worth investing in a high-end dual-core tablet, as this will guarantee that you have the horsepower needed to run just about every piece of software right now.
