If you’d like to be able to quickly switch on and off 4G on your brand new HTC EVO for whatever reason (saving battery etc), check out XDA forum member rdude‘s Android toggle widget.
Designed to work on any launcher or home screen including HTC Sense, Launcher2 or Home++, rdude ended up coding the toggle himself after an unsuccessful search for such a widget.
The apk is available to download free from the application thread. Alternatively, if you wish to donate to rdude, a donate version of Toggle4GWidget is available for 99 cents in the Market.
Currently, the app is only supported for the HTC EVO 4G.___________________
