Hi,

This is my first post on this forum so I apologise in advance if I 'jump in' too hard.

I found this thread via a Google search as I was having the same problems with BlackBerry Maps on Orange UK but following the advice re TCP, I set my APN as 'orangeinternet' and turned of my wi-fi connection and now have access to actual maps rather than the dreaded diagonal lines.

I only hope this helps someone else.
