Slower? Bummer... still real interested in Fried's pp of zero with all that RAM!!
(NK fix & C2 (Cookie 2 final) needed to flash again for me...)
...also anyone else (besides pcmanager) tried any of the other sense replacements?? If so, getting 120MB RAM? Fast?
*HOW TO! Step VII... (need cabs? Step VIII)
120 MB of RAM? Use a startmenu replacement above AND a sense replacement:
**HOW? Uncheck Sense: Start(winkey), Settings, Home (sometimes under personal), >> Items, Uncheck Sense (then check a preinstalled menu you want or, check "Windows Default", or leave blank & use a preset / preinstalled "startmenu" above which will also allow you to select all your programs & settings via the hard or soft winkey.
4 Phone Menus (Sense Replacements save RAM!) right here : ~takes me seconds to jump between 4 different home menus, all very small footprint (except Sense/Cookie)
settings, home (or personal then home), >> items, Check the one you want below
1. Cookie + Sense- download & burn a cookie ROM will have Sense ck'd by default
2. Titanium, Simply check "Windows default" (on the same ROM you're on)
3. iphone today (ignore the horrible name :>)) DL, install then select ck box
4. Easy today: DL, install then select ck box
