It will do nothing just exit.
U can now move most apps to sd card under settings.manage apps. Move to sd card!
May be issues like widget doesn't load. So try it and discuss!
Must be running froyo, must be rooted, follow command exactly.
Update*
After playing with it for a few hours I suggest only changing apps that are standalone such as games.
Leave the home replacements, active task killers, widgets or anything running in the backround.
After a reboot it may look like ur apps are gone. Just give them time to load from the sd card.

Nice C&P, but I found that "App 2 SD" works just fine, no need for the froyo ROM, and it only lets you move apps that can be moved, by default, so no moving system apps.

Ya like i am the ONLY member on here who C&P's stuff from other websites. And thanks for the find also

Yea, I know, I'm sorry, If I called out everyone who has C&P'ed I would wear out my keyboard, but is still A nice find if anyone fits the requirements

You can find a lot of it on their website. They have a lot of stuff on it. with mostly all droid phones.

I know, I did quite alot to my droid from reading and downloading from their website, well maybe not a whole lot, but I do have the Ultimate Droid ROM, Slayher 1200mhz Kernal, BlueMidnight Theme, Changed a few icons, and changed the Carrier ID (Verizon Wireless)

You can also install the app "Mod Install Location For Root" from the market. This app allows you to set where you want the app to install. It uses the froyo a2sd method instead of the ext3 partition method. I personally prefer the ext3 method because when I flash a new ROM I don't have to reinstall my apps. Mod Install does require root obviously.
