The iPhone 3.0 Beta 4 has been released and over on theiphoneblog they have been receiving several tip offs on finds within iPhone 3.0 Beta 4.
They state that the big news looks to be the mystifying “Store” which was bare in prior betas yet now has information inside.
Another is the camera which now apparently asks the Apple iPhone toting user if they like the image they just took and would like to save it or opt for a retake. Although they do say they aren’t sure if this feature is only implemented for MMS.
