Reason why ATT knows your tethering.

[mmaboi21]

I'm sure this isn't brand new news to everyone but I just wanted to share some info with you guys/gals about the mywi/att tethering issue. Below there is a forward from my buddy that works at att. I don't know exactly what he does but he asked one of his network guys how do they know we are tethering. Below is your answer, as far as a way around it not sure yet but I'm still waiting on a response from him concerning that.


Ps. I dont know why the pics are soo blurry.

The first pic is the one my buddy emailed, the second is from the network guru.

It seems that jailbreak tethering simply unlocks functionality already in the phone. By comparing the data type with your plan (which would lack tethering support), they can tell you're tethering.

Interesting it's called "Cingular".

You should forward this to the people that make tethering apps on Cydia, see what they think about it.

Good idea.

I shot them a message from their website because they only have twitter setup for their contact via Cydia. I couldn't put up the photos but hopefully they email me back so I can forward the messages to them.

I show the AT&T APN as "broadband" (for the iPad), I don't have an AT&T phone to look for...

Cingular makes all kinds of sense, they didn't change the APNs/rDNS/etc. from when they (AT&T) acquired Cingular (to see, run

$ dig -x 166.205.8.7 +trace

on a NIX-flavored system). Incidentally, this helps to confirm a lot of suspicion that AT&T is only watching APNs so editing the APN should be sufficient to mask tethering.

Awesome so there is a way around it..
I'll post as soon as intelliborm gets back to me. I'm sure they will have some sort of mask update.

Didn't cingular buy up ATT wireless? Then ATT bought Bellsouth which owned Cingular?

[mmaboi21]

My apple buddy told me today that the wap.Cingular is for older phones like the old cingular flip phones. I'm not sure if he's correct though... Any thoughts?

[confucious]

Using the apn is a very, very inacurate method. Very easy to fake and unlikely they even bother with this.

IMHO - they could be that stupid...

[mmaboi21]

How is it inaccurate? If you see traffic coming on one based on tethering then that means you tether??? I'm confused but I do know that this email is authentic. So why would they say something that is not true.
