How to Enable T-Mobile AWS LTE Support on Your A1428 iPhone 5

These are instructions on how to enable support for T-Mobile's AWS LTE network on your unlocked A1428 iPhone 5. The steps were first detailed by leimobile and only work for unlocked AT&T models or the officially unlocked model sold by Apple. They will not work for the Verizon iPhone 5.

The patch will only add support for T-Mobile's AWS LTE network. It will not add support for the AWS HSPA+ network. Additionally, you must be jailbroken. You can find instructions on how to jailbreak using the evas0n.
