I shall explain - my college has no wireless, and i needed to email some work to myself to print out (as plugging in a computer to the network is banned)

I created a wireless network on my MacBook, made my iPhone 3G connect to it. Nothing not a glimmer, after playing about with airsharing for 10 minutes and re-leasing the settings on the network (on my phone) i managed to make my phone tether itself to my computer.

I was online, downloading e-mail and surfing the web !
I have no idea how i did it, or what happened. We tried it with my friends MBP but had no luck the same procedure would not work on a MBP but would on my MB.

Odd, yes.
Amazing, yes.

But how did i actually do it ? Can it be redone ?
Can it be exploited ?
 
It is also noteable to mention that when connecting to the password protected network, the iphone did not ask for one when connecting, and when i followed the same steps with my macbook pro and steve and then my iphones it did, using identical wep keys
 
That's really interesting, and very cool! Have you been able to replicate what happened on a different day? Have you contacted the makers of AirSharing and asked them if this is some sort of hidden feature, or how it might have happened? I'm sure they'd love to hear your story.

EDIT: having just looked at your image I'm surprised you were able to get anything with those speeds...
 
The speedtest website did take a while to load, the youtube video is processing at the moment, it is bizarre and worked on 3g yesterday, it was only gprs in that test
 
Nice find! Anyone else wanna test this and confirm it? Maybe un-jailbroken tethering *is* possible without NetSharing!
 
This is partly the point, following the same steps as steve in the same room with my 3g and macbook pro i cannot get it to work! But have been witness to his doing it twice at college on 3g and 2 times at my house... hence why it is so bizarre, if anyone else has any luck i would be pleased to know what the missing piece in the puzzle is!

Is his iPhone jailbroken?
 
yes my iPhone is jailbroken, but has no tethering apps installed !

However, Cydia could have installed something that unlocks the iPhone's ability to send cell data to a connected computer. Just the fact that your iPhone is jailbroken tells me something. Do you know exactly every file that PwnageTool or QuickPwn modified?

True, but surely somebody would have found this prior to me.
Please also note i tried this with my iPhone on my friends MBP and it would not work.

Hmm... weird. I kinda wanna try it. Have your friend try his iPhone on your MacBook and see if it's a computer problem or an iPhone problem.
 
Um, that's just internet sharing. You're sharing the internet connection your computer receives to other machines using the computer's wifi card. It is possible to create an ad-hoc network without a base station and using just your computer.

Nothing out of the ordinary here unfortunately.

Im sharing it from my iPhone to my computer, i thought that was deemed impossible and bad hence why apple pulled NetShare

Oh right, from your post it sounds like you're sharing internet from your computer to your phone.

That is new...
 
That's not new. You can share the internet connection from your computer very easily.
I don't think you understand. He said in the original post:

He has no internet connection at his college yet he was able to get online through the iPhone.
 
I just tried it.
My steps:
-Created a new network on my MacBook named "iPhone Test" w/o password
-went to my network settings on my iPhone and connected to "iPhone Test"
-opened Air Sharing on my iPhone (note: at the bottom, it showed my air sharing address)
-I attempted to open Google on my MacBook using FireFox

Results:
-I was unable to connect to the internet on my MacBook from my iPhone using these steps
+My iPhone is not jailbroken
+My iPhone said I was on 3G
+I have a flat black MacBook Core 2 Duo


Am I doing something wrong or is anyone else getting the same results as me?
