Re: [Cputuner-development] Feature Idea: Switch to 2G if Wifi connected

Hi Dennis

OK, you are lucky...
Since Cisco released anyconnect for rooted phones, I have wifi switched
on most of the time, this saves me some battery and gives me heaps of
bandwidth.

OK, let's try it.  I sort of got addicted of saving battery even though
it is not that important by now...

Would you mind writing up some docu for it?

I wish I could leave my phone on my desk all day!

Attached you will find a development preview of 2.7.0 (which might be
3.0.0 when released). My changelog states the following:

* features
- make configuration loadable from other apps (with the correct permission)
- ask before deleting autoload configuration
- change networkmode on wifi connected
* bug fixes
-
* internal
- new networkmode handler

Except the code switching the network mode I run this apk for days.
