If you're having trouble sniffing out a proper WiFi Access Point from where you're standing, then you might find this nifty little application for Apple's iPhone and iPod Touch rather useful. Called APlogger v1.0.5, it's a native application that scans for hotspots in your area and keeps a ready log of Access Points for easy reference.

Developed by Chris McDonald, this homebrew app includes several other features that make it quite versatile for the iPhone user on the go:

• summaries of the most recent scan and all past scans since invocation are displayed.
• detected APs are logged in a tab-separated logfile for offline analysis. Logfile names are expanded using strftime().
• the current location may be enumerated and is logged with each AP entry (sorry, no GPS support yet!).
• one-off scans, or periodic "auto-scanning" at a chosen rate, may be requested.
• the detailed view of the most recent scan may be sorted by SSID or RSSI.
• the WiFi interface may be turned on and off with a simple control.

As an added note, while APlogger has the ability to keep a list of logged AP entries it does not help crack WiFi WEP or WPA passwords, nor does it retain or inject any WiFi packets.

For those of you interested in this application, you can download the APlogger.app file from QJ.NET's download section accessible through the link below. Make sure to insure install the entire folder in your iPhone's application directory and set the binary to chmod 755, if necessary.
