Since firmware version 3.1, iPhone users on Telecom’s XT network have been unable to use their iPhones as a tethered PC modem.
Geohot has now released his latest jailbreak and unlock – BlackRa1n – for iPhone 3.1.2. The difference with this against all prior 3.x hacks is that it unlocks the iPhone’s baseband, meaning the user has full control over all network and data settings. In theory at least, this would mean tethering can be enabled on the Telecom XT network.
Is anyone out there brave enough to try this?
