Just a quick one this time, I recently threw together another app that uses the 118100 open API, this time it's a web app for iPhones that's a available at http://numbersearch.digibuzz.net.
It's pretty simple and straightforward, you just go to the webapp URL in Safari and add it to your home screen. When you search you get a list of the top 10 hits and by tapping any of the hits you get some additional info on the hit and a button that you can tap to dial the number.
As before the numbers are all swedish numbers since that's what's in the 118100 database.
