My market install crapped out after 30 apps or so with 0.6 install so I went to Titanium Backup and must have inadvertently restored too much, overwriting newer google apps, etc. (Why is there no option to automatically prevent overwriting newer google/system apps? Or did I miss it?)
Just installed 0.6.1 without wipe and it's a brand new world, even at stock 800 mhz. Wow! It friggin flies, plus I got the new Market app., finally. No need to overclck now for me. Thanks Pete!
