Christ....climb out from your arse.
Wow. Thanks for that. Makes it all worthwhile
Maybe if Owens had started his question with 'I have installed AppSync for iOS 4.0 on my phone and have the most up to date version but itunes is still deleting my apps/games. Can you please help?' there would have been no need for the sarcasm.
Owens if it still isn't working try going into cydia and re-installing Appsync (Cydia, manage, packages, Appsync, modify, reinstall). If that doesn't work try uninstaling it (Cydia, manage, packages, Appsync, modify, remove), Do a hard reset (hold the home and power buttons together until the screen switches off, let go, then power the phone back up) then go into cydia then install it again.
If that doesn't work try uninstalling installous and appsync and install app sync before you install installous. Maybe installing installous before appsync isn't allowing appsync to work as it should
