I just got my 8310. It was locked into Vodaphone (Australia) but the guy at the shop is a friend of a friend and he unlocked the phone so that I could use it with my Optus pre-paid.
I noticed it has a GPS receiver- cool! When I go into Maps, all I get are grey diagonal lines. Do I have to purchase maps on top of the phone cost now??
Also, how do I turn down the colume on the keypad? Oh, how do I check the OS version?
In the About menu, my phone says:
V18.104.22.168 (Platform 22.214.171.124)
Is my OS V126.96.36.199? What's the "EDGE" part mean?
