I have a weird problem i was hoping you guys could help me with. For some reason, while I'm at home, on wifi, everytime I wake my phone up (not sure if it's doing it while it sleeps or not, but battery has gotten worse, so probably) the 3g comes on for about 15 seconds. I see the grey sync arrows come on in the top left. When I pull down the window shade, it pops up a little notification saying something like "phone book contacts are up to date..." or something like that. But it always activates 3g even when I'm on wifi. I even disabled background data and auto-sync and it still did it after I woke it up. Didn't receive my gmail while those were disabled but still tried to sync my phone book with something. Sometimes I can watch it sync the phone book 5 or 6 times in a couple of minute time frame and sometimes I can watch for 10 minutes and it won't sync once... Any ideas?
