Ok just a little info (thay should be added to someones sticky im sure) about Vista and activesync
To disable USB activesync in vista (since vista uses sync center instead of a seperate activesync tool) you have to launch "Windows mobil device center" and Uncheck "allow usb device".
This us VERY important if you have bricked your device...
I have bricked and unbricked my device a few times now...
if your stuck at the bootloader screen (USB/SERIAL 2.xx) and keep getting errors connecting to the device (101 102 or whatever error) just turn off USB connection in the mobile device center and try again
Make sure you use the proper bootloader when creating the rom (thats how i bricked it the first time)
