Samsung Galaxy I7500 :: Overclock At 610 - Constant Fc Messages

Although the promise of an Android phone is still exciting to me, I have to admit my first experience is leaving me less enthused. I was finally able to do the magic 15 second driver install and got 1.6.3.3 installed without any seeming issues. Since then it's been a long road. 1. The phone overclocks at 610, but definitely is unstable at 710. 2. I get constant FC messages. In accordance with a posting I found somewhere I got MinFreeManager and changed the defaults to: Foreground 8 Visible 10 Secondary 10 Hidden 24 Content 26 Empty 24 and that seemed to help. I also am using ADW, and wiping the Launcher.apk in /system/app seemed to help. But it's still a problem. 3. Audio and Bluetooth are problematic. I wiped the default Music.apk and tried Meridian which does seem to deal with the headphone bug. But mysteriously Meridian often plays one or two songs and then just stops. And Bluetooth A2DP is erratic and full of gaps. 4. All of these would be surmountable if it actually worked consistently as a phone, and that's were things that getting bad.......
