[sceptr]

I have been searching for days on several forums for a few answers:
I have a Sprint Touch Pro 2, which I have unlocked and run T-mobile on it. For a custom ROM, should I use a CDMA or GSM?
As far as other uploads with radio distinction, should I treat this as a CDMA or GSM phone?
How do I disable the Handsfree Activation message at startup? (I've seen this question asked, but never answered.)
I don't know which forums to use for these questions and I don't want to brick my phone.
Please help!
