Hi ya all.
One simple question... I'd like to change my Pearl with the new 8800. Since all my friends and customers have already my PIN of the 8100, if I'll take the 8800, my PIN will be changed right (I guess the PIN is something related to the device and not on the SIM card). Is there a way to set the new blackberry on the same PIN of the 8100. Of course I understand that in that way it won't be possible to use the 8100 anymore, since I guess there couldn't be two devices with the same PIN.

Thanks alot, Diego

Not possible.
The PIN is tied to the Blackberry device. You can't move it to another device.

The PIN is the internal serial number of the unit. One per BB no duplicates
