Sorry if this is a repeat thread, but I did a search and didn't find my answer. For those who have upgraded to A012, do you need to keep Bluetooth on in order to prevent the unit from locking up like previous versions?
No you don't really need to keep it on. In previous versions the only trick you needed was the fake exchange server trick. You may still need to use the fake server trick to keep your battery from draining on A12. I still use the fake sever trick to keep activesync from starting up on its own.
