What do you mean stuck? I've been running 3.5.something for months on end now... As to some of the touch cabs, they are available here... some of the others just dont work.... Here's a link to them...
http://www.ppcgeeks.com/touchflo-t6067.html 1/2 way down, and the really good one,
http://forum.xda-developers.com/showthread.php?t=311225 that has a ton of em.
Now, I'd make a good backup of my contacts and my phone usnig spbbackup and pimbackup, and be ready to hard reset if one of these installs totally hoses it up.
I know that the updated camera still isnt working, but the dialer, commmgr and taskmanager are working good.
Good luck.
