Here give me a few, I have work tonight but I can scout around when I get home later. Your phone can likely handle rooting it, not sure if there is a ROM out for it with ICS (4.0 if I'm not mistaken).

You should be able to check if you have a update by going into Settings<Software Update. Try it on WIFI I think some phones will only do that over WIFI I know my old HTC Inspire was like that so it could be a HTC thing. Looks like most the ROMs are for GB (Gingerbread 2.2 I think).
