Is anyone starting to hate their iPhone l am?

I am so sick of my friends constantly sending me mms msgs and I cannot see them unless I write down the info and go to the website! I still can’t figure out why apple would do that! Don’t they know how routine mms sending/receiving has become for some? My phone has also been freezing up lately and I have no clue why. My iPhone is hanging on by a thread here. One of the only reasons I don’t want yp get rid of it are for some of its other features. Why haven’t we had a software upgrade in so long? Can you relate?
