i totally agree with the OP. ive wipped every way 10different times trying different 2.2. from the first leak to roms and 2.1 just plain works better. my phone runs way hotter, it reloads every damn web page if i leave the browser for anything and come back.
the rom im running now defaults to 700meg and its still super laggy after a few days. i normally set cpu to min 550 make 1k to get close to stock 2.1 feeling.
i reboot a few times a day, but it doesnt really help. hell even my boot screen lags a few times lol.
someone give me 2.0.1 gallery, 2.1os and flash and id be happy. but 2.2 isnt all its cracked to be up for me. but flash makes it worth it, i guess. flash plays laggy too, but im hoping that gets better.
