The infamous iPhone DevTeam is now back with a newer version of redsn0w which brings support for IPCC tethering hack for iPhone 3G and 3GS only. This IPCC tethering hack enables you to install carrier bundles that aren't officially signed by Apple on the latest iPhone 3.1.2 firmware. With this, you can connect your iPhone (3G and 3GS only) with your PC or a Mac in a way which enables your PC/Mac to connect to Internet via 3G network on your iPhone.
Last week we posted a complete step by step guide on how to enable Internet Tethering option on your iPhone 3G/3GS running iPhone firmware 3.1.2 which was based on the hack, originally found by the Dev-Team. While the hack worked flawlessly for some, many specially AT&T users were forced to choose between enabling either Tethering option or visual voicemail (VVM). Follow the steps below to enable both Tethering and VVM on your iPhone running 3.1.2 firmware.
Internet Tethering is a process which allows you to use your iPhone as a wireless modem to share its Internet connection with a computer via USB cable or Bluetooth interface. There have been several hacks floating around the web to enable this functionality, specially for AT&T users in the US, however, the latest iPhone firmware 3.1.2 has blocked all those hacks which means that tethering will no longer work for you if you have updated to firmware 3.1.2. Fortunately, there is an app called “MyWi” which can enable tethering on all iPhones (including 2G/3G/3GS) running 3.1.2 firmware with just a touch of a finger!
