Guys,

Mine is iphone5 and since i got it on Sunday the 3G signal will be lost completely and i cant get any data.

Even if i move around to outside or another location few km away still the same problem.

ONLY way to get back 3G is to turn off the phone and turn on again.

THIS SUCKS !!!

I am on Maxis.

Any other bro have similar problem?

Update:
The 3G issue on my phone seems to be gone now.
After i updated to newest iOS version.

Although the OS update says its for Wifi issue only but it seems to cure the problem.

Are you on the latest iOS version?
After i updated it kinda seem to solve the problem and its been ok since.
