Here is a new original video for you guys made in house. The video will show you how to safely update the iOS firmware on your iPhone or most other iDevices using PwnageTool. By updating using PwnageTool, you can preserve your old baseband. If your old baseband was unlockable, you can still unlock it even with new iOS firmware installed, which is why PwnageTool is so great.

The video also explains how to use Tiny Umbrella to save your old SHSH blobs so you can downgrade your iOS version later if you wish to do so. Using Tiny Umbrella, you can save your SHSH blobs without even jailbreaking your device!
