Here is what I would do:
Backup the old device
Insert sim and mem card from old device into new device. Don't turn on the wireless radio yet.
Restore the backup from the old device to the new device.
Turn on the wireless radio and then activate on your BES.
Once that's done you'll still need an application installed to use GPS. BBMaps can be downloaded from http://mobile.blackberry.com
. You can also use Google Maps found at Google Maps
If you want a better turn by turn, voice prompted application then you can use TeleNav but there is a $9.95 per month subscription for TeleNav. Nice program, though.
