New and need some info

[cosmanja]

Looking for a bit of info. I've been doing some searching on the forums but can't seem to find the info I'm looking for.

First I have the Canadain Bell HTC Touch phone which I gather is the same version as the HTC Vogue except we're not GSM. I currently am running Windows 6 Professional build number CE OS 5.2.1620 (build 18125.0.4.2). From everything I understand Bell Aliant in Canada hasn't enabled the GPS functionality of the phone (am I right in saying this?). Since the GPS isn't working would it hurt my phone to flash it with a ROM that has GPS enabled?

I've been looking at the different roms and quite a few of them had caught my eye and I know the process is to unlock the phone and then install the ROM but is it pretty much the clear cut? I've seen a few different phone unlockers; which makes me question which one I should use and such.

I'm knew to the HTC Touch ROM's and quite interested in getting involved in it. Any information you guys could help me with would be greatly appreciated.
