I have always had odd wakeup's while driving (roaming in and out) and sometimes over night. But it always went back to sleep on it's own.
Since updating to the new Sprint ROM it wakes and won't go back to sleep on it's own.
This applies to the recent Sprint ROM and the AKU 2.2 ROM. They both do it. It only does it when charging (I think possibly only when it's fully charged green light).
I have installed:
VC 1.6
Memmaid
WP 2.5.1
Resco 5.42
SPB Pocket Plus 3.1
Mapopolus
AIM
My config.txt looks something like:
