Ok, I am making the jump to Sprint from ATT, and conversely - to the Hero from the iPhone. I depend on the following items heavily so if you see a problem forthcoming, please prepare me with a little bit of advice to make the transition smooth. 1) Calender synced with MobileMe - plan is to go to Gmail and sync contacts, mail, and calender. My calender is very very important to me. 2) Mail. I will be syncing a web account from work, Gmail, and Comcast mail. Can it handle the three separate accounts. 3) SMS - it is the quickest way to make contact and verify appointments. 4) Yellow Pages Mobile The value of the video and music is a nice feature, but I seldom used it on my iPhone. I am a big App hater, as most apps are superficial. I have been with the iPhone for 3 years, and have seen only apps that are mainly to entertain with little real long term purpose, so the app controversy will not dissuade me a bit in my purchase. Thanks in advance all.
