While I don't use the 3G part, after upgrading to OS5, the bluetooth does not recognize anything and I lost my folder where I put the camera app, and other apps. It is completely gone. Oh well I am taking it back to Apple in a few hours since the white edge is seperating from the rest of the unit. This will be the fourth return, the other three were returned due to really bad backlighting issues. I am beginning to think I should have just kept my 1st ipad and waited for ipad 3!🙄
