Chevy's didn't work out too well for me. Phone started getting super laggy, froze a couple times and started getting hot quick.
So, I went back to P3 LV 1100, SetCPU at 900 interactive... and man! tell you what, this is working out awesome! Everything is smooth, battery life is well over a full day with decent use (some calls, surfing, apps, etc.), and temp stays pretty nice and cool (low 70s).
Now, all I'm waiting for is 4.3... LOL! The "want" never ends
Good luck, guys!
