Thanks for the welcome. I paid for my phone up front with PAYG - then inserted a pay monthly SIM (so the number changed) with the credit being brought forward from the PAYG to up I had to buy. So I suppose that is why Orange Maps and Orange email don't want to play. Very soon the number should change again with PAC. I shan't touch Android until that kicks in, in case I have to go back to Orange. In the meantime, I shall lurk around the San Francisco forum, and learn before I leap.
Once again, thanks for the friendly greeting.
