I have a HTC Evo 4g LTE (jewel) and have a custom ROM on it. I've been through about 5 or 6 trying to find one I can send pictures with. What I've just noticed is that when I use ##DATA# and try to change the MMS Server URL then menu and commit changes it always said no changes to save. I looked in MMSC Settings and it would always have the Sprint.com, so I edited it from there and saved it and it actually saved the setting. I was able to send a test picture to myself and it worked for the first time since I rooted my phone. After the first message though they all time out and will not send even if I retry. Any thoughts???
I've tried using go sms pro and handcent but neither will load my contacts or save them if I input them myself. Guess I epic fail at those : /
