Before I got my iPhone 3GS – I did try tethering with my friend’s unit. He is a Maxis customer and using an official Maxis iPhone 3GS. It worked. As I was using my Sony Vaio W to access the net – I just had to install iTunes to get the connections going. Before long, I was surfing the net via his iPhone 3GS’s data connection. So, when I tried tethering with my DiGi data connection – I noticed that the Tethering option is not there.
Since I was at Pavilion, went to DiGi Centre to enquire about it. As usual, the customer service personnel looked at me as if I was speaking in tongues. Long story short, this dude said DiGi doesn’t provide tethering support for iPhone but Blackberries. Knowing how “knowledgeable” they can be – I relied on Mr. Google instead and found steps provided by fellow DiGi users to enable this feature. It requires me sending a digi.mobileconfig file to myself and opening it on my iPhone. Simple enough. File sent, opened and installed – but still, the Tethering option is still not available. Contacted the thread starter and hoping he might know of a new way or file. My guess is that the latest 3.1.2 firmware on my iPhone 3GS disabled this bypass. If any of you out there, know of a way – please please please let me know. I need tethering – badly. Thanks.
UPDATE: Got a response from the thread starter. According to him,
For firmware 3.1.x above, tethering has been disabled and only work with the contracted telco which is Maxis. We are still loooking for solutions for other telco users. May need to wait for sometime mate.
UPDATE 2: DiGi responded to my Twitter enquiry and confirmed the same.
