iPhone data tethering with redsn0w 0.9.3

iPhone’s latest OS 3.0 and 3.1.2 firmwares have already gone through the jailbreaking process, but folks who have done so would have discovered that they can no longer tether their iPhones. Fret not, the latest redsn0w 0.9.3 iPhone jailbreak utility is able to enable the tethering capability. Once redsn0w is executed, you will still need to download a custom IPCC file (carrier bundle) that informs you whether your iPhone is allowed to tether on a given carrier.
