If I bought an unlocked 3G iPhone, could I still use EVERY feature?

Question

I am looking at buying an unlocked 3G iPhone and use it on t-mobile. If i bought one, could i still use every feature or would some features not work? What features would not work? thanks!

Of course, you wouldn't be able to claim your apple warranty on the device. Other than that, everything else should work. If you are paying for a data plan on T-Mobile, you should be able to use data. Beware, however, if you are not, as they will probably charge you somewhere around $.01 per kilobyte. If this is the case, use BossPrefs to turn OFF EDGE and 3G, to use only WiFi and bluetooth to access the internet. Otherwise, your phone constantly uses data in the background, without you even knowing it.
