HELP! Can't use phone after trying to get mms working

[nonzero]

I have an Alltel Mogul (ppc6800) flashed over to cricket, and I had the internet working, but mms didint work. I followed the instructions as this link, http://forum.ppcgeeks.com/showthread.php?t=25859 but I was missing some of the files in my registry. I called my friend to get him to try and send me a pic, but it didn't work. I reprogrammed it (*22, still nothing.

I couldn't get online any more after changing the settings.

Then I followed the instructions at this link: http://www.howardforums.com/showthread.php?t=1251812
I did step 6, editing the PST settings

"Mobile Directory Number : Your Full Cricket Number
Min1: Your Cricket Number with out the Area Code
Min2: Your Area Code
MSID: Your Cricket MIN Number goes here
Ture MIN1: Your Number without the Area code
Ture MIN2: Your Area Code
True IMSI_S: Your Number with Area code

If your SPC is not 000000 Then please go to PRL, Click Update PRL file, Go to Menu, Edit, Find the PRL on your Memory Card once that is done go on to the next part.

Next go to Security
HDR AN AUTH USER ID : Your number @mycricket.com
PPP User ID Your number @mycricket.com
PPP Password: cricket"

and..

"WAP Set Up

1. Go to Start, Settings, Connections, Connections

2. Go to Mange existing connections, at this point you can make a new one or edit one, I did edit, Rename Alltel to Cricket or Cricket WAP, Dial String should be set to #777, Username is Your Cricket Number @mycricket.com, password: cricket After that hit done.

3. Next Go to Proxy Settings, Make sure that Both boxes are checked, and for the Proxy server make sure you type in wap.mycricket.com, Go to Advanced then delete the Socks entry and change the port on the HTTP to 8080, it should also read wap.mycricket.com. After this make sure that save and after that go to Internet Explorer and go to a website, at this point if you can view a website i.e google.com or some other website then your good to go. If not please go back or feel free to PM or post."

I tried to get online, mms, nothing. Then i tried *228, and it couldn't reprogram. Now I can't even make a call.

Can someone please help me. This is my business phone, and i really need it.
