Well apparently no one has taken the time to read the packages you send in with your information....that black jack info is so wrong for the iPhone, but it did help me figure out the main problem....
First research stuff before spreading bogus fixes and rumors....if anyone had read those files you would know why you can't get it to work. That file says the phone is what it isn't and does what it can't....so that's like throwing a baseball to a guy with no f*ckin arms. He wants to catch it...but just doesn't have the right equipment.
IT IS BECAUSE IF YOU DON'T HAVE THE FAMILY MMS PLAN YOU NEED YOUR WAP PUSH ENABLED AND YORU VLR RESET.....HOW MANY TIMES DO YOU HAVE TO BE TOLD??!!?!?!? THAT IS IT....EITHER MMS PLAN OR WAP PUSH ENABLED AND STOP CHANGING THE SETTINGS THEY ALL WORK WHEN THE IPHONE IS CONFIGURED CORRECTLY.
FOR EXAMPLE HOW MANY OF YOU EVEN KNOW TEHRE ARE TWO DATA PLANS FOR THE IPHONE....ONE HAS A LOT MORE WIRELESS CONNECTIVITY....HENCE WHY SOME OF YOUR PHONES WORKED. There was an error at AT&T when teh 3G came out and some of ou were given the enterprise data plan for iphone when you signed up for basic unlimited.
So.....let's not hear anymore about your damn settings,....it's not the holy grail
