I would like to make a sugestion to see if the right eyes see it maybe some one can make a program,(available in cydia), to unlock frequency bands.

if im not mistaken, tmobile blasts 3g/4g signal at 1700mhz. at&t blasts 3g/4g signal at 1900mhz. maybe some one with the right knowledge can make a program that will unlock the feature to choose either frequency.??

Any suggestions, or maybe point to someone that can help? :iphone4vert:
