T-Mobile announced earlier this week that the iPhone 5 would be coming to the carrier, which marks the first time that T-Mobile has officially carried Apple's phone. However, while AT&T models of the iPhone 5 can be updated to support T-Mobile's AWS bands, jailbroken iPhones can't be tampered with in such a way, or else the jailbreak would be lost. However, a new jailbreak tweak fixes this.
If you're jailbroken and want to make your AT&T iPhone 5 compatible with T-Mobile's LTE network, there's a new jailbreak tweak that allows you to do that without messing up your jailbreak status. All it takes is adding a repository to Cydia, installing a patch, and editing a bit of text. There's 15 steps in total, which can seem daunting, but take it one step at a time and you should be fine.
However, do this at your own risk. If you're jailbroken, then you probably will be familiar with the process, but it's a bit more complicated than most jailbreak tweaks. As in, it's not as simple as downloading a Cydia tweak and installing it. You'll have to open up iFile and dig deep into the phone's file system to edit some text files.
We wouldn't be surprised if a handful of AT&T users switched over to T-Mobile and brought along their iPhone 5, so this tweak will definitely be of use to all those jailbreakers out there. T-Mobile's plans are something we've never seen before in a major carrier, so while it is a bold move for the company, it may catch on quickly.
