While the software unlock scene hasn’t been active since quite some time, there might be some good news for folks who are stuck with on an iPhone baseband that isn’t unlockable.
A number of sites have started selling a permanent iPhone unlock solution that doesn’t need users to jailbreak their iPhone and simply requires the device’s serial number and the IMEI code.
The solution as detailed by provider Apple n Berry:
Apple N Berry iPhone IMEI unlock is a permanent iPhone unlock solution. Once unlocked, your iPhone will remain unlocked even after an iOS upgrade or SIM card swap. IMEI unlocks are considered an iPhone factory unlock that works with any AT&T iPhone model 3G, 3GS, 4, and 4S regardless of baseband.
Our IMEI solution is not a GEVEY™ product and requires no extra software or hardware to unlock your iPhone.
The solution, as sold by Apple n Berry, comes at a price of $150.
Another such provider, iRepairIndia, sells the permanent unlock solution at a price of $85 and claims to complete the unlock within 3-48 hours of the request.
Please note that we’ve not been able to verify the method. It is also not clear how exactly this method works so please proceed with caution. Please also don’t forget that if you’ve an off-contract iPhone then you can request AT&T to unlock your iPhone for free.
