Whatever you do, DO NOT get the Sprint iPhone. It is PAINFULLY slow. There are a lot of complaints on the web about the speed. I just switched to iPhone 4S from Android. Using the same network and location (my work), an app that normally would take 10 seconds to download on my Samsung Epic (using the same 3G network, not 4G. 4G takes 2 seconds) now takes 10 minutes on iPhone. I'm not kidding.

I am so annoyed with it and I've only had it for a couple of days. I'm even thinking about switching back to my old Epic and use the iPhone strictly for when I travel aboard. Well, I guess the only good thing about the Sprint iPhone is that they unlock the SIM slot for customers who have been with them for more than 2 months.
