Apple has suddenly and inexplicably subjected the App Store to its whims, once more. This time around, it's Wi-Fi hotspot detecting apps that have been removed from sale.

Apple hasn't given the developers of the removed applications much clue as to what they've done wrong, saying only that they were "using private frameworks". The ban only applies to apps which scan for networks - not those which let the user search for nearby hotspots based on their GPS location and a database.

The developer of one such application, WiFi Where, told the Register: "We received a very unfortunate email today from Apple stating that WiFi Where has been removed from sale on the App Store for using private frameworks to access wireless information".

Apple has become increasingly heavy-handed with its App Store regulations of late, pulling almost all which contained any kind of "objectionable content" except the ones from large publishers. While the App Store remains the largest platform for mobile applications, Android is catching up fast and repeated moves like this could have a serious effect on its future viability.
