Update without USB

[jbeauls]

Does anyone know if it's possible to update my phone to 2.3.3 without using the USB port? I had a water incident with my phone some time ago and the micro USB port is no longer functional. I have an external battery charger (with extra batteries) to keep me going but would love to be able to get Gingerbread. Anyone know if it can be done? I have an unlocked X10a running firmware version 2.1- update 1 on the Rogers network in Canada. Thank you for the assistance, it's greatly appreciated
