Just to be clear" YES it is fully possible to use the Treo Pro on Verizon without HardSpl/Unlocker/etc. It DOES NOT require an ESN swap, and is MUCH simpler to do than an ESN swap. However, there is chance the procedure will not work (very small chance). If it fails, an ESN swap would be required but is honestly not very difficult in the case of the Treo Pro. Once again, the steps required to do so are HIGHLY illegal and violate a few federal laws.
