Are you still stuck your iPhone 3GS with 4.1 firmware....?
No application support due to the old version....?No money for Factory Unlock( to upgrade current version )....?
Don't worry... You dont need to get Factory Unlock. I can upgrade your iPhone 3GS to current version 6.1.2. After upgrading you can get any software from iStore without any matter . No deference from Factory Unlock phone.
First you need to sure that your phone is Factory Unlock or not. I can give you some clues to find it.
- If you update it with iTunes without any matter thats mean it doesnt have a lock. If it has a lock after updating phone cant be use as like before update. Dialing pad only.
- If your phone menu has "Cydia" application and Its modem firmware 06.15.00 ( To check Settings> General> About> Modem Firmware) 99% your phone locked some carrier.
So now if you have a Factory Unlock phone you can update it. But if you patch unlock one its not easy. If you want to get 6.1.2 version contact me.
