SE Xperia X10 mini/mini pro refuses to show the channel number for WiFi networks in any application I tested. For example. WiFi Analyser is a tool for Android phones you can use to find the least crowded channel for your WiFi network. This app only shows "Unknown" in channel info. Other apps displays "Unknown" or "0". Does anyone know anything more about this problem? Edit: Fixed in the 2.1 update!
