Officially, no. Tehcnically it should be possible though. The technology between Sprint & Verizon is similar. For this to work, you need Sprint to put the ESN (phone's unique identifier) into their database to activate the phone. This isn't always as easy as it sounds, because the provider's don't like to do this. That said, it should be possible. You may want to check out the treo forums; www.treocentral.com.
