Hoping someone can tell me if this will work, or is even very functional. I am with Verizon, but recently signed up with T-Mobile, love the idea of digits and would eventually like to switch over. So now I have a T-Mo SIM, can I put it in slot 2 on my VZW phone, and what functionality will I gain? Is it easy to switch from SIM to SIM? Any help is greatly appreciated! Thanks, Scott
