Looking for help and Info!

[Rauwt]

I am a new Imagio user and I am looking for customizations and some fixes to a few things. I haven't ever done any reg editing and from what I have read in the forms it happens alot. I am kind of a noob when it comes to phone apps and files. I have always thought that my phone should be like a high tech pocket knife. So any cool app I find I like to add.

So im looking for some info on a good free reg editor. what are roms and what do I need to add them? Are all HTC TP2 apps compatible with the Imagio. Is there a good list of apps for the Imagio? what are the minimum requirments when looking for a compatible app?

I have a totally stock HTC Imagio with a 16g memory card.
