AT&T Tethering Disabled in Latest iPhone Beta

Apple has disabled AT&T tethering in the latest iPhone beta released to developers on Tuesday.

The iPhone OS 3.1 beta 2 disables a popular tethering hack for the AT&T network. The hack works on iPhone 3.0, even though AT&T does yet officially support it.

The hack enables data tethering (and sometimes MMS) by altering the iPhone’s IPCC carrier files. It’s easily enabled by visiting sites like BenM.at using mobile Safari on the iPhone.

AT&T has promised tethering later this year, but has yet to release details. The company is expected to be enabled in late summer and cost about $15 extra.

Thanks QuickPWN.
