Haha does anyone even read this thread.
The update is done directly through your iPhone safari browser. It's installing a carrier update directly, no iTunes.
Just to confirm, 2G iPhones don't allow MMS or Tethering to show up in the settings area.
This works for Tethering, but not MMS.
Where do you paste the info it tells you to copy?
I can go settings > general > profile > more details, but after that i can't edit the advanced settings...
