Thanks for the answers so far. I still find a BB very unintuitive. I've worked with computers for 20yrs but I find BB logic very different. I've looked around it and find internal instructions just don't match what I find.
For instance, I found something about synchronizing SIM and address book.
It starts by saying 'go into address book and click on menu'.
When I go into address book, there is no menu and I think one would have been reasonable anyway. All I see is the list of names, topped by the word 'Personal' and 'Find' top left.
Using the Blackberry button only gives options for the highlighted name, not the list as a whole
If a menu would show for some of these things I could make much more sense of it.
