Flashing for iPhone 4 Sprint to Page Plus

There still is no working CommCenter patch to bypass signatures to allow this flash on iOS7. I have seen several posts online and have tried every method, all with the same end result...it didnt work!! If you have a Sprint iPhone 4 and it is still on iOS 6.1.3 or below, this can be done, bad ESN or not. Feel free to contact me with any questions.
