For those that don't have Root Explorer (and are cheap like me), you can also do this just using adb.

Plug your phone into the computer, make sure USB debugging is enabled, and DON'T mount the memory card. Open the command prompt and type the following (replace C:\somewhere with the folder you want to use):

adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
exit
exit
adb pull system/build.prop C:\somewhere

Go to the location you chose above, open the build.prop file with notepad and change line 6 to:

ro.build.version.sdk=7

Once that's done go back to your command prompt and do this (once again put in the actual directory after C:\):

adb push C:\something\build.prop system/          
adb shell
su
mount -o remount,ro -t yaffs2 /dev/block/mtdblock4 /system
exit
exit
adb reboot

That's it! I'm no linux or Android expert, but that worked for me!

Thanks nerdherd. The live wallpapers are pretty cool.
