I have a locked iphone 3gs 16 gb bought from US from ATT. Actually bought thru ebay. Can I use this phone in dubai with any official carrier like du without unlocking.
Yes. If you unlock the AT&T network locked iPhone 3GS from network restriction, You can definitely use it with any other GSM network. To unlock an iPhone 3GS visit ClassicUnlocking.com and get the remote unlocking service. This method of unlocking is safe, simple, affordable and permanent. IT doesn't require a jailbreak too. Good luck.
