Update to iOS 6.1.2 is not happening on a brand new factory unlocked iPhone 5

I have a brand new factory unlocked iPhone 5 which was recently purchased. I am unable to upgrade iOS 6.1.2 on this new phone. The current iOS on this phone is 6.0.2. I have placed a local carrier SIM and it is working. Currently phone is in working condition with iOS 6.0.2 and I am trying to upgrade to iOS 6.1.2 which is the latest one. Kindly share your thoughts or experiences in upgrading to iOS 6.1.2 success.

iPhone 5, iOS 6.0.2

Thanks for highlighting this Peter. I have checked from Aprtonix store as well and they have confirmed with IMEI number that it is factory unlocked. They have asked me to try updating the software using WiFi connection directly on the phone. I will try and let you know if the problem still exists. In the mean time do you suggest any other method to upgrade the phone?

Yes Peter. I will certainly check with Apple first whether it is "Factory Unlocked" or "Carrier Unlocked" as I could use local Airtel SIM card in it without any problems. I have purchased my ealrier iPhone 4 also from eBay and I could successfully upgrade all iOS in it till now without any problems. I will try to restore it full and also using DFU mode in case requied. I will not come to know whether it will reset to its original carrier unless I could restore it to the next version. Will keep you posted on my fidnings so that we can ensure some traction in this mail thread till resoultion. Thanks for your support in this regard.

I could successfully restore new iPhone 5 from my earlier iPhone 4 backup when my iPhone was using iOS 6.0.2. When I try to restore from iPhone 4 back up with iOS 6.1 it is throwoing an error as iPhone 5 was not upgraded to iOS 6.1. First I need to update new iPhone 5 to either 6.1 or 6.1.2 directly and then only I can restore from my earlier iPhone 4(with iOS 6.1) backup.
