Would the Sprint PictureMail work for Alltel MMS though? Sorry for being so obtuse, I'm just new and starting to frazzle myself a bit... might be time for a smoke break.
Another thing I noticed - not related to the problem at all - but my phone locks out the data connection when it's plugged into my computer, and seems to use my cable internet for browsing instead. I'm quite sure it wasn't doing that yesterday before I flashed from the stock ROM, and man am I impressed.
