I finally go to the step where it says "Internet Tethering" pn my 3g with 3.0 ATT. But the problem is when I try to enable it,it says call ATT to enable this service??? and in Cellular Data Network Screen on iphone, it shows APN=wap.cingular and then username and paswork...what could that be? ANd MMS=wap.cingular MMSC,username,password,mms proxy,all that crap.What am I doing wrong?

Tethering and mms worked on AT&T for about two days. Now when I send a picture, it puts a small red ! mark next to the pic, if I select it, it tells me the message was nitsent and asks to try again. No longer working now. Same thing for tethering. I could tether for about two days, now when I plug the iPhone in, (winxp) it sits at aquiring netwokr adress, but never connects.
