UPDATED: TCP Port Scanner App for Windows phone: Now Available!

Microsoft Just approved my TCP IP Port Scanner application. It is available for download. This allows Windows Phone users to enter in a combination if DNS Names +IP Addresses along with a list of ports to scan and get a list of which ports are responding. The Scan timeout is adjustable.

Note: Some 2G/3G/4G Data providers may artificially cap the TCP timeout. If you get false positives or negatives over the phone's data connection, try turning down the timeout value (about 5 seconds seems to work for me but YMMV).

Requires: Windows Phone 7.5 and a data connection (WiFi and/or cellular carrier).

Update (27-Jan-2012): Version 1.1 improves reliability of scan results.
