CDMA TP2 for use only with GSM, what happens if I install'it custom CDMA ROM

[neckcromante]

Hi,

I previusly search for this on the forum, dont find anything similar.

I have a HTC Touch Pro 2 Sprint Version with stock rom WinMo 6.5, I only use the phone in a GSM Network (Telcel) dont have a data plan, just WiFi for the moment.

I want to use a custom ROM like Migthy ROM or Energy, if I install any of this ones, would I loose GSM functions??

Thanks in advance
