If I unlock my iPhone from TMobile and use it for Verizon?

No, sorry. T Mobile uses gsm technology and Verizon uses cdma. Two entirely different technologies.

You mean, you want to change the network in your iPhone? For that, you should remove the network lock that is on your phone. I suggest you can approach http://www.unlocking4u.com/apple-iphone/rs6wp9/ and specify the country, locked network and get their permanent remote unlock service. The iPhone uses only GSM network and hence you can't use Verizon network which is CDMA.Hence after unlocking the iPhone you can change to other GSM networks or still if you are persistent in using a Verizon network then try to get yourself a CDMA supported obile phone.
