My friend sends me mms from his Droid x and they show up on my charge with the play arrow but when I play it it just shows the audio file and a still pic of the video but plays fine on his and that's stock mms as well as handcent!
Im with you there. I love the phone but the support isn't great. I bought the phone on an impluse while I was on vacation and we went in to get my sides t-bolt looked at. Im pretty sire when the bionic is released I'll buy one as well.
It may be that the videos your friend is sending you require video codecs that are not installled on your phone. Try installing RockPlayer Lite (free) multimedia player and see if the videos run in software decode mode (not hardware decode mode).
