It is rooted, but you can't move all apps 2 SD. It depends on the app. I can back up any app on the SD, but not run them all from there, unfortunately...
Boo to my phone! I uninstalled the updates because I had a different version than you, like 10.2.156.xxx I think I got it from applanet. So I reinstalled the updated in the Market, still no option to move to SD. What gives...
Try app 2 SD. Your phone needs to be rooted for it to work. If your runnining CM7 under CM settings>application you can check to have apps moved to external storage. Just keep in mind not all apps can run on SD. App 2 SD will also clear your cache as well. Very useful app. Hope this helps you.
