hi guys. i just bought an iphone 3G and my problem is, when my iphone is connected to the pc via the usb cable, all my sms received while connected will be delayed to hours & sometimes people can't call me especially after sync-ing.
it doesn't happened all the time but it often happened.

any1 having the same prob as mine?

i just deleted all the app i've installed from Cydia and re-installed some. so i'm checking if the problem persists.
