Now you can turn your Palm Pre into a nifty 3G router over WiFi. jkOnTheRun notes that with My Tether 1.5 for webOS, you too can share your EVDO signal with any device that uses WiFi (i.e. laptop, iPod Touch). You will need to root your Pre, enter developer mode, and have the latest SDK installed to get it working (see procedure here). However, version 2.0 (available with a donation) includes an installer which should make things a lot easier. Previous, more crude methods of tethering have been available for the Pre, but this one should be a step up.
My Tether 2.0 supports custom wireless network SSIDs and WEP encryption. Check out a short video after the break, or head over to their homepage for more details.
