PPCGeeks - Alltel touch pro data/mms issues

So i have an alltel touch pro stock rom 6.1 and i have been having a few problems.

First i came from having a diamond and love the touch pro but on my diamond i had it set up to where data connection would never be turned on except when i ask it to. I though i had it set up the same way with my touch pro, weather is only when i tell it to, email is only when i tell it to but for some reason i will have my phone off (screen off) for a while and ill pull it out to use it and a data connection will be open.

I have looked high and low to find something that is telling it to turn on but i cant figure it out, so if somebody knows what i might be missing please let me know.

Secondly
recently i have been having occasional issues recieving mms. I have never had a problem sending, and i will recieve some messages but others i get a dialogue box that pops up. It reads "cannot connect, dialed:#777, Cannot connect for an unknow reason. To check your connection settings and change them if needed, tap settings, If the problem continues, reset your mobile device."

I also sometimes get a message telling me that my username and password is wrong and i need to fix it. I have not changed any settings and when i check my username and password they are blank. There is also a domain (maybe it says server i cant remember) blank which is also not filled out.

So any clues on what the issue is. I cannot find anything thats wrong nor anybody else with this problem and it gets annoying because i will recieve a MMS message and then 10 minuest later i cant recieve another one and when i try to download it doesnt work.

Any insight would be very helpful, thanks.
