If not then the visibility of this feature may be disabled when you activate your iPhone.MacBook Pro, Mac Pro, Mac OS X (10.6.4), Studio: Maya, Mudbox, FCS, Unity3D, Time Capsule, iPhone 4.
Currently Being ModeratedOct 3, 2010 11:35 AM (in response to wilsonchuhk)i live in Hong kong. turned on internet tethering via bluetooth & noticed it was missing from my iphone 4!
I tried to use my iphone 3gs for internet tethering & it also vanished on the spot soon as i tried to connect to its network via bluetooth.
experimented on restoring my iphone 3gs if it will come back, and it did.
but soon as i connect to its network via my macbooks bluetooth, it vanishes again.
could this be a problem from the latest macbook update?Macbook Unibody, Mac OS X (10.6.4)
Currently Being ModeratedOct 3, 2010 11:43 AM (in response to MacERA10)Tethering is a carrier feature and while the iphone is capable of tethering, tethering will only appear as an option if your carrier supports such through a carrier file. So, contact your carrier.MacBook Pro

I can't find any reference to internet tethering on their website so I presume that they don't allow tethering.MacBook Pro, Mac Pro, Mac OS X (10.6.4), Studio: Maya, Mudbox, FCS, Unity3D, Time Capsule, iPhone 4.
Currently Being ModeratedOct 4, 2010 8:15 AM (in response to wilsonchuhk)Yes, I am with Three Telecom in HK. I inquired about it, but the guy who was assisting me doesn't seem to know much about tethering so he asked me to bring my phone to their shop tomorrow together with my macbook to see what's wrong.Macbook Unibody, Mac OS X (10.6.4)
Currently Being ModeratedOct 4, 2010 8:24 AM (in response to MacERA10)According to this document, 3 offers tethering. However, the option to tether will only appear if the appropriate carrier file has been installed on your phone. So, connect your phone to itunes & hit the "Check for Update Button" to see if 3 has released a new carrier file. If none is available, at least you know what to say to whoever you talk to.MacBook Pro

This might be a little late or a stupid comment but, did you all look under network? The personal hotspot doesn't always show up on the main section of settings (settings>personal hot spot) and is often found in settings>network>personal hot spot... just a thought and not too sure if this is what you are looking for exactly. Good luck!

You may have to switch it on from settings area to use it. For instruction how to switch it on see here:

did you found/got a solution?
That thread is really old, but I found the reason e.g. for some SIMs not working with tethering (not blocked by the network):
1. 3 (Three) HK (Hong Kong) ist not working, because the wrong APN is stored on the card. It's mobile.three.com.hk stored on the card, but should be imobile.three.com.hk. That can be changed for "normal" APN but tethering is stored separate...
2. U Mobile Malaysia does not set any Tethering APN at all, it must be set manually with my3g and no credentials at all
3. Finally some cards are really blocked. Sorry to say, but that's only possible to be workarounded with other Smartphone like Android (or Jailbreak for sure). It's somehow sad, that network operators still do not allow tethering on their networks, although most plans are traffic based, so it's customers decision, isn't it?
