So I have been using iOS 4 for about a week now, and it’s a nice step forward for the platform. Today it officially came out, and according to Engadget it is the same as the GM release. I have been having trouble with updating my carrier settings to Rogers 7.1 and as a result my data connection is not working. I am now restoring the phone and will not restore the backup I have a feeling that might be the fix. I will update this post if that resolves the problem.
Update: Yes it solved my problem.
