No sooner has iPhone 3.0 Beta 4 been released, then our tip-lines have been filling up with finds. So far the big news looks to be that that mysterious “Store” tap, icon-less and empty in previous betas, now sports user info.

Also, the camera is now polite enough to ask if you like the photo you just took and want to save it, or if you don’t and want a chance to re-take it. Note: we’re not sure about this change yet, it may only be implemented for MMS, and may have been around in previous betas (lots of maybes, we know, we’re trying to sort through everything as efficiently as possible.) If it is system wide, some of us will lament the loss of our ability to rapidly snap photo after photo without the interruption of requesters…

(Thanks Andrew and anons!)
