My current phone is the Blackberry Tour (Alltel) and I will soon have to switch to AT&T so I am looking at either the Samsung Captivate or the IPhone 4. Im not a big Apple person, but do have an IPod Touch so somewhat familiar with the layout. I have been reading many negative things about the Captivate and I guess I am looking for some additional insight. Here are my concerns regarding both phones... Reception Issues(IPhone), Battery Life(Both), Vista/Windows 7 compatibility(Both) and a big one would be Email (Both)...I use my phone for work so email is a huge concern..(Hotmail, Outlook-Microsoft Exchange). Have good friend using the Incredible(Android 2.2) on Verizon without any email issues..Help??
