Is there a BB9700 techno nut that can help me? I bought my (unlocked) BB9700 in the Middle East and registered with Q-Tel local provider in Qatar. My GPS works fine in Qatar, however, when I go home to Perth Australia GPS seems to be working but does not show any street maps just diagonal lines and �No Data�. My local provider in Perth is Optus. How can I get the GPS to work at home?
