What exactly is this tweak doing? I found to save battery, you can go into your phone settings and change the network type to CDMA only. This saves battery because when the phone is in it's default global mode, it searches for GSM networks that you can connect to but it will always find none in the US. (Assuming your using this phone on Verizon!) If you change the network type to CDMA only, it will never search for a GSM network, saving you battery.
