I'm not running that app but I have noticed when I manually switch WiFi off I can see 3G has been in a sleep mode because it then wakes up and starts to connect. I'm only guessing though this is similar to what your doing?Exactly, and when i'm not using my phone for anything else but music, i have switch pro installed to switch off 3g data. This one trick alone would give anyone 10 fold on their battery. When i'm on lunch or on my way home i switch 3g on, check my mail and what not, then toggle 3g off again.
This is just the little things i'm use to doing do to the bad battery life i got on my og.
Okay rant over...
