iPhone 3.0 software was finally released yesterday and one of the new features is “Internet Tethering”. Enabling tethering with Mobily is not possible according to this image:
I contacted Mobily’s support and the employee told me to install “pdanet”! PDAnet is a jailbroken application for the iPhone! Let me say it again, Apple’s authorized iPhone distributor in Saudi Arabia is RECOMMENDING jailbreaking the iPhone which Apple say is illegal and voids the warranty!
The iPhone 3G is sold by Mobily in Saudi Arabia for four months now and their employees are still ignorant about what the iPhone 3G can and cannot do. So your option is to follow this guide which requires having iTunes 8.2 pre release or do what the Mobily employee told me, which is jailbreak the iPhone and install PDAnet!
Enable tethering iPhone 3G on Mobily
Thanks to Abdullah for posting the modified mobileconfig file. Just download the mobileconfig file on your iPhone 3G (mirror), or download it to your computer then email it. Now you can enable tethering.
To enable tethering go to Settings, General, Network, Internet Tethering, slide to ON. You can connect using the USB cable or bluetooth.
Update: From Abdullah: Mobily configuration file is for post paid plans only.
