"3GS, more memory, sync with iTunes, and a lot of apps"4.0 starson by jatibi
Pros: A load of applications and ability to integrate with corporate email. Decent battery life. I don't need a blackberry.
Cons: Call quality and internet speed are highly influenced by your area. AT&T is good in some areas and not so good in others. iCal integration with mac-mail is incomplete for a smart phone. Tasks and invites can't be responded to in phone
Summary: In South Florida I never drop calls on my iPhone, but in San Francisco it occurred a few times during a one week visit, but people I was working with confirmed it was an ATT issue. I have had Verizon and TMobile with similar results in different cities. I like the iPhone, I upgraded from the 1st Generation iPhone and the 3GS has a much better internet response. I almost don't read emails a lot of times on my PC. iCal is featureless for a calendar app so I use Google calendar. Overall I am very happy with the phone. Not moving to iPhone 4 as it seems to be the same model with just a couple added features that I won't use. Hoping they improve their calendar integration with OSX which right now only syncs, but not all items. (to do's are not syncd)
