I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
And just how, exactly, does one find a copy of Swype for the EVO and install it on the Thunderbolt?
follow the instructions from 21stnow above. i don't believe you actually need an EVO copy. just go to their site and sign up. they email you the install file.
Go to www.swype.com and register for the beta group. You will receive an email that will have instructions for what you should do next.... that is what I did also, and had to enable install of non-market apps in order for it to work
