Hello, I simply don't have the time to research all that. I have a couple of questions: The company I work for wants to switch phones. They think about transitioning from Blackberry 8830 to the iPhone. The Blackberries are running all the stuff GPS/Email etc. and it works great. How about the iPhone. Is it POP3 compatible out of the box? If not what apps are recommended to be used for POP3 Email? Are there limits of how many POP accounts you can setup per phone? Are there proper turn by turn GPS systems available for the iPhone? How fast is the internet on AT&T? Does anyone have a comparison between the internet speed of the 8830 (Sprint) and the iphone (AT&T). What does the iPhone better than the 8830? If there are any ex-Blackberry users, maybe you can chime in. The company got a great offer today so they need to switch fast. Thanks in advance!
