Hi guys,
I've started development on a port scanner for Android. It's currently in early development stage, but works and is a useful tool to have with you on the move.
I plan on improving performance and the user-interface in future releases, but anyone who wants it can download it from here: http://www.seanobriain.com/android/Fiosru-0.5.apk
I also plan on developing a few more network tools for android, so if you think there's anything in particular that Android could do with - let me know. Would love some feedback in anycase :)
Thanks,
Seán "Coscair".
