Hi,

I have AT&T iphone 3GS running on iOS 4.1 and 05.13 .04 Baseband. I have purchased factory unlocking IMEI service on eBay which the seller claims to work on basebands earlier than 06.15 on 3gs.

My question is can I upgrade to latest iOS 6.1.3 via iTunes now without chance of re-locking it, as i assume when i upgrade to new IOS, my baseband would be changed to 06.15.00 ?

If anybody has any idea, please share.

Regards,
