att is enabling sideloading, the updates are coming out over the next week. i dont think there is anyway to tell if you have received it or not unless you try installing non android market apps

 

If you go to Settings>Development, you should see "unknown sources" when you receive the update. I do believe you'll actually have to check for the update, my phone shows nothing as of 10:35pm Central.

 

the updates are supposed to be automatic, like when the android market updates. and if what i heard is correct, there will be no check box on the captivate

 

Do you have to un-root to get the update?

 

hmmm...why would anyone unroot to get this update that is already available on the rooted device?
