My iPhone is currently jailbroken on firmware 4.3. This is tethered JB and I would prefer an untethered one such as the JB for 4.3.1.
However, I cant seem to upgrade my firmware via iTunes as it keeps on popping up with an error. Is there a way of upgrading it a different way to allow for the untethered exploit?
I'd prefer not to restore the iphone to factory setting if possible as I believe i'd need to reinstall apps etc, and all my stored emails would be lost.
Any advice is appreciated.
