Hi OpnSrcAddict,
The Blackberry Pearl does not have the DUN bluetooth profile required to communicate with the N810 as a modem I believe. The only Blackberry that does this on Verizon's network is the Storm. I recently just upgraded to the Storm from the LG Dare because the Storm has the DUN profile needed for tethering with the N810 (also costs an additional $15 on top of the $29.99 for unlimited blackberry data, and is still $15 cheaper than going straight up mobile broadband connect), and is the only Blackberry on Verizon's network that is EVDO rev.A. Unless you completely object to the storm, a lot of people do, I would recommend that device to you. Or if you want to go the non-smartphone route, try the LG Dare or Versa. They are the only non-smart phones with Verizon that have high speed EVDO rev.A data. If you need a phone, I have a one year old LG Dare for sale that works beautifully with the N810 for modem use. Let me know, and good luck.

Joe
