Not sure if I am of any help..

1. I have a mac at home and a PC at work. I use Entourage at home on my mac. So I can easily sync with my Entourage and BB using pocket mac. You can set up pocket mac as a bi-directional sync or one way...which you may wanna do...if you have new
device down the road, you can easily sync back to a blackberry for example.

2. If you have a PC, you can use desktop to "back up your " your files...within the files there is the address book which contains all your address book info on your bb.
You can easily ..if you have a new BB, move over that address book "only" into your new device..by exporting that file out to your "new" blackberry..as it is a selective restore.

If you are talking about information stored on the "Simcard" itself you maybe out of luck...I think...unless you export simcard info on to the phone book/address book first and then sync to whatever.

Hope this makes sense...if you can get a hold of a PC with the desktop installed, you can even back up your BB to a memory stick..and later extract from that memory stick your address/contact..
