In fact, the BB Bold and the new Tour on VZ come from the factory that way. They are really GSM phones that VZ installed VZ SIM cards that are locked to each ESN. Both the devices and SIM cards are locked so what you cannot do is take a TMobile or AT&T SIM and put it into a VZ BB Tour. Conversely, you cannot take a VZ SIM card and put it inot any unlocked GSM device, it has to be locked to the the ESN of that device. Evidentally, VZ still operates enough GSM towers (and leases time on others) that this works for them. This is an interesting alternative for folks that need to usea GSM device (like an unlocked IPhone from New Zealand) on Verizon's network. If you are a pre existing VZ customer call them up and tell them that your employer is now going to make you use their GSM device but you want to keep VZ's network. THey will ask you for the ESN of the GSM device and if they can get a SIM card locked to it they will put it on their network. Pretty interesting, I was not aware of this until the other day.

My friend did this with his iPhone. What you have to do is unlock the iPhone (obviously) and hack the Verizon sim card that comes with the BBtour and just retain the PRL information for the Blackberry on the sim-card while wiping any link to the original ESN...this is how Verizon thinks the phone is a Blackberry. But you also have to block the iPhone from sending its information out to the sim card and then to the Verizon towers. Before you ask this is VERY, VERY, VERY hard to do, and as far as I know less than five people have ever gotten it to work. If you're not a computer science major or don't know how to hack a sim card then please don't ask me how to do this, because I don't know. But it is possible, and that's what you have to do. Verizon uses GSM for SOME voice, you get lots of dropped calls but data works great. This is what would account for the crazy data speeds, but like I said voice sucks, it's really not worth the effort.
