Hi,

This happen 2 days ago, using maxis set IPhone 4 32Gb, when i try to update my apps using 3G. it just didint respond when i press the update..and when press home to main screen the app is blank with the status waiting..

I thought something wrong with my iTunes account so i logout., but cant seem to login after logout, it states check network connection or retry. can see the 3G is loading when login but after 5-10mins it states retry.

I thought maybe is the 3G connection, so i try to surf using safari and also open FB app, it all works fine. no problem.

i was using iOs4.3.3, but last night updated to 4.3.5 and still having this problem. I have never used Jailbreak.

BUt when i turn ON WIFI to connect, i can login to my itunes account, no problem, even can install and update apps.

sigh... what the hell happen. please help.    

If i were to restore system, does it only restore the OS, or it deletes everything and restore to factory setting?   

I think yesterday before it updated my Os to 4.3.5 itunes did a backup.

my apps all all sync, but those files not too big so no problem. just my songs is over 10Gb and will take some time to load in.

so if restore, do i have to sync my songs again?
if i recall correctly restore got 2 option right, new phone or ?? like that..
