Dear All,
As you know, the iPhone OS3 is supporting MMS and Interner Tethering. The problem is that the .ipcc files available on this from apple now, do not cover STC Saudi Arabia.
I have found some STC_sa.ipcc files here and there but they all have the same problem, either the MMS or the Cellular Data Setup is not correct.
That is why Allah helped me to develop this .ipcc file that has the correct setup.
Please consider that if you change any data in the iphone->General->Network->Cellular Data Network, Internet Tethering will not work.
You can revert back using RESET SETTING button on the same page.
Have fun all with the new iphone Carrier Configuration.
