I had the same problem of not having the Web Access menu item. I enabled it by changing seem 0032_0001 offset 51 to "1" using P2KTools.
Once Web Access was there I was able to add new browser and MMS settings. However, I still couldn't get MMS working even after using settings on the AT&T help site and various other sites (different sites showed different settings). That's where I'm stuck now -- anyone have a solution?
I too have a razr from t-mobile unlocked using att sim card couldn't get pictures or videos to receive or send went to att site then to forums then media net had someone with same problem they gave him a link to click on it was for a v3i so i typed for v3 can send and receive but havent figured out internet yet but really dont use it on my line
