If your iPhone is jailbroken, check out MyWi - a neat app that lets you create a wifi hotspot by sharing your iPhone’s internet connection for free.

There are other jailbreak apps that can do this (like PdaNet), but MyWi is by far the easiest to use, fastest and most reliable available.

10 day free trial to road test MyWi, then a one-off $9.99 charge if you want to use after free trial. Money well spent in my book.
