Enable T-Mobile on Your AT&T iPhone 5
Earlier this week, T-Mobile announced that they will finally be getting the iPhone 5. As we reported a few days ago, T-Mobile will have to sell a tweaked version of the A1428 iPhone to support their AWS bands.
Existing iPhone 5 models are not yet equipped with the AWS bands needed to support T-Mobile. While the devices don’t have the AWS bands, you can get your device ready by having an unlocked or Jailbroken iPhone. If your iPhone is Jailbroken you can follow these steps to add the AWS bands to you device. Note that this will only work with the AT&T iPhone 5.
1. Open Cydia
2. Tap “Manage” and then tap “Sources”
3. Tap “Edit” then tap “Add” and put the following URL into the text box: https://v.backspace.jp/repo
4. Once the URL is entered in tap “Add Source” and allow for it to download all of the repo’s info and packages.
5. After your iPhone has refreshed, tap the v.backspace.jp/repo field or go to the search bar and find the package CommCenter* patch…
6. Once you have found it, install it and then reboot your iPhone once completed.
7. After the iPhone has restarted, open Cydia once again.
8. Search for iFile. The free version includes basic features. You will want to purchase it to take advantage of all of the features.
9. Once you have found it, install it. No reboot is required, though you can do it just to be on the safe side.
10. Once iFile has been installed, close Cydia and click on this file from your iPhone and click “Open in iFile”
11. Once you’re in iFile tap “Unarchiver” and 3 files will show up above T-Mobile LTE.zip
12. At the top, tap “edit”and tap the dots with a check mark next to carrier.plist, overrides_N41_N42.plist, and overrides_N41_N42.pri
13. Tap the clipboard icon at the bottom and tap “cut”
14. Now tap “done” at the top and tap the house icon at the bottom then tap Library, then tap Carrier Bundle.bundle (the one in blue), and then tap edit at the top again and tap the clipboard icon. Tap “paste” and it will auto inject the carrier files into the carrier folder overwriting the other files. (you may want to make a backup of these files incase anything goes wrong: overrides_N41_N42.plist, overrides_N41_N42.pri, and carrier.plist)
15. After the files have been placed, exit iFile and restart iPhone. After the iPhone restarts, allow it to acquire signal and display the T-Mobile logo then go to where you edit the APN settings (Settings –>General–>Cellular) Once that is done, enable the LTE toggle and you’re good to go.
Now you can run T-Mobile’s service without having to buy a new device.
