I've been away and I see many changes have been happening. I'm unclear as to what to do with our 2 phones as far as firmware/hacking. Would anyone be able to advise the right course to take with them?

Husband's Phone: AT&T, 1.0.2 (want to go to 1.1.1 and hack it via Installer)

My Phone: 1.0.2 Hacked via Installer. No AT&T but Youtube, etc. works due to cheating it w/Husband's SIM. Would like to upgrade to 1.1.1 and re-hack. (what order of steps is best?)

I'm just unclear as to what's working and what's not right now but I'd like to accomplish the above and fear mucking it up. I appreciate any advice. Thank you.
