Hi! I'm relatively new to the iPhone market, and, even though it is a powerful phone, I'm only looking to 1) Make calls, 2) Check my email, and 3) Stay online (hopefully) all the time on MSN and AOL applications. I spoke to a gentleman at an AT&T store, and he said that the phone will indeed run "some" apps while asleep. What I'm wondering is, which application to people find to be the best and most effective for chit chatting on MSN & AOL, and can they stay online even while sleeping? - Thanks so much!
