Just would like to know has anyone encountered the same problem.

Last time, I was syncing the phone to a PC which is connected to Internet. At the same time, I forgot to off Wifi on the phone. Syncing with iTunes works well at the start and suddenly it stopped and said that an error occured.

Not bothered with the problem, thinking that probably it's a normal connection issue, I was surprised to know that it seems that the syncing was only halfway with 90% of my apps and games gone! The remaining apps still there on the same springboard but all other apps has already gone.

When I open each of the remaining apps, all works fine and game data still intact. Thank God, all apps still in the iTunes, it's just the apps has been uninstalled from the phone. In the end, I have to install remaining apps and tediously put every app one by one on the correct springboard that I want.

Apps gone still ok, problem is game data is gone. Means I have to start all over again to play long gameplay like Assassin's, DH etc..Most annoyingly important confidential data in 1Password has gone as well.

Can somebody care to explain what could be the culprit? Is it really because of the wifi turned on?
