I installed Afterburner 3.2 recently. I just got the 7135 and have been slowly adding more progams. I just took 2 years off from Palm (was on company PPC). I experienced some lock-ups after installing Afterburner (my first one lockups with the phone after 3 weeks of usage) so I slowly backed off on settings. I now have only slow Mpx and adjust ticks checked. My LClk/2 is 24MHZ. I have Beyond Contacts components, HourzPro clocked at 43 and have had no lockups for days.
I'm running X-Master - the only hacks are Pop and Fitaly Stamp in addition to afterburner.
