HTC Touch Pro 2 Houdini question

[pur123]

I am a newbie here and have a question.
If I have a sprint HTC touch pro 2 working on Metro PCS and decided to try using TMobile GSM (after SIM unlock and other steps needed), will I have to houdini it again when I move back to Metro PCS?

Thank you in advance for your help

You can keep it set up to work on metro and put in a tmobile sim, and select gsm only to use tmobile's network. If you ever decide to go back to metro just select cdma only on the phone.
