Sorry this happened to you...It is the number one complaint I have heard from folks who have upgraded to iOS 4..

What has been working for people...

Connect phone to Itunes, backup, sync data to external apps, restore as new, resync or restore from backup..

Should work..

A lot of users have reported success by changing the APN....Apple will not tell you that since you are in the US with a locked phone...

This thread shows you a website that you can use to change your APN..
