Sony C905 and GPS questio

Hi! I have a debranded C905 (they don't sell them with contracts here in my country), I already flashed to the latest firmware and everything (smile shutter, google maps 3.0.0 and so on) but I have a problem that persists..

I can't use the GPS without data transfer... If there's a wifi signal the phone doesn't priorize it over data transfer, it always want to use data transfer.

Is there a way to make this phone work as a real GPS, without using data transfer??

Thanks!!

you can just set a fake/false data setting and set that to be use. therefore if they try to connect using your data account it wont be possible and should be using the wifi then.
