As I am annoyed that Mikrotik does not show channel numbers along with wireless freguencies I made small and simle Android application that shows this info. It comes pretty much handy.
You may download it from http://pedja.supurovic.net/projekti/wifi-toolbox. Article is not in english but aplication is. I could not put it on Adnroid market, but installing it directly on the phone is quite simple. Anyone who uses Mirktoik should be able to manage that.
