hi all, I have an iphone 4 that i updated to ios 6.1.2, I preserved the baseband on 04.10.01, the device is jailbroken with sn0wbreeze. The question is I would like to unlock my device so it can be used on orange (it is currently locked to 3uk). What is the best cheapest way to do this? Factory unlock is £110 so cant afford that. Is gevey sim ultra the way to go? Will this work well on ios 6.1.2? Any input would be great, thanks.
