Angry Sync phone book all the time?

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?

By default, wifi will shut down when the phone sleeps and turn back on when it wakes up. Try changing the Wi-Fi sleep policy. Go into Settings, Wireless and network, Wi-Fi settings, perss the menu button and select Advanced. Tap Wi-Fi sleep policy and set it to Never.

Sorry, I should have stated that I already have wifi set to remain on. 3g coming on during sleep isn't the problem. The problem is it trying to sync my phone book (over 3g) all the time...I also just did a full reboot (vol up/down/power) and it even tried to sync the phone book after it booted up (again over 3g). So when this happens, both wifi AND 3g are up at the same time. It's also using small amounts of data (I believe) because from the time I went to bed to the time I woke up (wifi on the whole time) it had used about 48k of 3g data.
