Stick it to the man – Enable MMS on AT&T for U.S. users right now!

If you hate the fact that AT&T is the sole reason that iPhone OS 3.0 is not going to be everything it could be at launch, take matters into your own hands and give AT&T the cold, hard, digital shoulder.  Don’t worry, you don’t have to be a master programmer or dive into system files.  All you need is a spare “dummy” AT&T phone.  With that phone do the following: 

u can enable ur MMS settings… just do this….
-take sim out of iphone
-place into old ATT phone w/ MMS capabilities
-make a call or send a message
-check ATT site and see if phone changed
-go to https://mymedianet.wireless.att.com/
-with sim still in decoy phone register number on the website
-enter 4 digit passcode in decoy phone
-take sim out and put back into iphone
VIOLA~~~~~~~

So now we have the MMS open and ready as well as tethering.  While the MMS is less harmless than the tethering hack, I’m sure by this point you could care less.  Right?  Stick it to the man!
