I tried to upload some screenshots but this forum seems to be fussy about the size and it's limit makes for some pretty grainy shots. There really isn't much to look at with teh Wifi Detector as it is just a applet with some config screens. Best to just download it and give it a try. I could seem to use the 770's Opera to download and install the app. I just downloaded it on my desktop and transferred it over.

My impressions/observations:

Pluses:
- nice integrated unobtrusive little app
- works well with your existing network data
- handles autoconnection when the cover is taken off seamlessly so battery conservation is handled by simply closing the 770

Minuses:
- yet another applet on the limited space toolbar ... this could probably have been combined with the old network app easily ... maybe will in the next OS update
- networks that are hidden do not show up in the settings ... I am not sure if they show up in the scans
- don't know how to add new apps to start on connection list but I would imagine that there is a config file somewhere ... just not exposed on the UI AFAICT

Conclusion:
It's a keeper. Small and handy enough to find a permanent home on my 770.
