HTC Touch Pro Question

[victor__rojas]

Ok I tried searching for an answer could not find, I APOLOGIZE they pouint that I posted in the wrong section

I got a HTC Pro Touch from Sprint, I first Unlock then install Mighty Rom 5 after I took it to the store to flash (Metro PCS corporate) they flashed it nicely. BTW I am in California.

MY QUESTIONS:

1. Is the new Mighty Rom compatible with Metro? (the list doesn't mention it but the 5 neither had it but a friend had in on his so i install in on mine)

2. Do I have to unlock again before flashing?

3. If I flash the new rom WILL I GO BACK TO SPRINT SERVICE? (meaning I have to reflash to metro)

I know newbie question, I apologize if I bother anybody by my ignorance

Thanks

EDIT: So I understand that the ROM will work fine (hopefully as well as the 5 did) but boredandtattooed mention that it can change the pri back. is there a way to change it back again? btw any suggestions on Metro PCS roms?
