I hate to bump this but I thought I had MMS working... I can send messages. But I can't receive them. I've changed my MMS settings but I still couldn't receive. Anyway, I found this
post and thought that may be a fix. Unfortunately, step 1 wouldn't install in a different thread I found that it wasn't 100% necessary to uninstall MMS so I continued to step 2 that installed. Then step 3 didn't install so I gave up. The only difference is in the Connect via tab Alltel Wireless now exists. I don't understand why I can send but every time I receive a MMS Message it says Failed to Download.
Thanks
