I am a brand new subscriber to AT&T coming from T-mobile. I noticed coverage area is better with AT&T than tmobile by looking on their coverage map websites and also experiencing dropped calls quite frequently around the islands. I do travel to Kauai and my tmobile unlocked iphone 3g doesn't connect as well as my friend's AT&T iphone 3g. Anyway, don't want to stray from the topic. Is it necessary for applecare for an iphone 3GS and ATV? I do plan on keeping these till they die pretty much.
