I've been using Handcent SMS for messaging ever since my Original Incredible and never really tried the stock messenger on the Rez. Today for no reason at all, I used the stock messenger app to send a picture and it went through without 4G being turned on. When sending MMS using Handcent I have to turn on 4G or the MMS never goes through. Has anyone else experienced this and is there a way to fix it? I've checked through the Handcent settings and can't find anything that would fix this. Any suggestions?
