My solution : Deactivate "Cellular Data" and deactivate 3G.
I have myself encountered my share of issues while setting up Google Sync for i Phone.
The setup itself was fine but it took forever to sync my contacts and calendars.
Later on, it came to my attention that it could have been Google’s issue and not i OS 4’s.
So what can you do if you encounter the kind of issues mentioned above? Now if you’re still experiencing issues, you might have to go for a more drastic fix: restoring your i Phone to a fresh state as opposed to a backup. Sure you will have to start from scratch but your i Phone operating system will be as clean as if it just got off the box.
