Made my Samsung Fascinate freeze up and use more battery.
Amazing! Got me through the day while letting my social networking apps stay up-to-date! 6 stars!
Messed with my bluetooth audio
Lags the crap out of my Droid incredible
No problems, seems to be doing what it says it does, LG VORTEX
Made my N1 really slow. Uninstall.
Slows down the phone... Uninstall...
Battery life x 1.85 woohoo! Would be nice if the "keep data on for certain apps" worked
