hey i just put 4.5.0.77 on my alltel 8830. i have never had mms on this phone but now there is a option for mms. i send a picture and the person never receives it. they try to send me a pic and i never receive it. i get the check mark showing it has been sent.. i pulled the battery twice now and its still not working. any suggestions? maybe i missed something. on by the way sms is still working...
