Now I can ask this question: What are some of the best sites/methods of jailbreaking your iPhone?  I'm mostly interested in installing an app that will allow me to tether my iPad to my iPhone to tap into the 3G network so I can get on the internet with my iPad anywhere I have a 3G signal. I realize that Apple & ATT will not release an App to do this so they can capitalize on making more profit by NOT allowing it.  I have also read that it is definitely possible to do this if the iPhone is jailbroken and there are apps out there to do this.  However, there are more reliable sources to obtain the jailbreak method, so who are they?

4.0 PwnageTool 4.01
iPhone 3G

If you have a Jailbroken iPhone 3G at 3.1.2 (but not jailbroken with Spirit) then you should create the ipsw with PwnageTool 4.01 and restore from recovery mode or DFU mode.
If you have an out of the box iPhone 3G you should restore using a PwnageTool 4.01 ipsw using DFU mode.
If you have a Jailbroken 3.1.3 iPhone 3G it is very possible that this can fail from recovery mode, if this failure happens you will need to restore using DFU mode.
As an alternative to PwnageTool, you can use redsn0w on iPhone 3G (on both Windows and Mac) as mentioned in our last post.
