@SMed79, it would be advisable to downgrade your baseband to 5.13.04 by redsn0w as then you will have better GPS functionality. Click jailbreak, and tick only downgrade baseband. Then download 6.1.2, go to extras-even more-restore, choose 6.1.2, and redsn0w will ask to put your phone in DFU mode, don't press next, just press both home and sleep button for 10secs, then release sleep and continue to hold home button for another 16secs, and redsn0w will exploit your phone with limera1n and then you will be on 6.1.2 but stuck in recovery mode. Don't worry, Download ipsw 6.0, and in redsn0w go to select and choose 6.0, go back, click jailbreak, check cydia and let the process happen. Then you will be on activated jailbreak 6.1.2. Install ultrasn0w from cydia and you will have a working phone.
