Hi all,

As I have a unlocked firmware 2.0 early iPhone in Australia, but as I am using one of the sims from an official iPhone carrier Optus (or really VirginMobile) there is no Edge setting menu.

Found the work around in a blog: vowe dot net :: Pwnage 2.0 released

* You need to borrow a sim from a carrier that doesn't have any iPhone plans
* then place the sim in your phone and voila the Edge menu appears, now called "Cellular Data Network"
* change the Edge settings to your sim supported value (VirginMobile Aus => virgininternet)
* then replace the sim back to you own and it will work
* avoid letting iTunes download auto carrier settings just in case it clobbers the settings again.

Hope this is helpful, took me a lot of searching to find this easy fix.
