Apple will soon begin shipping a new version of its AirPort Express portable 802.11n base station, capping a recent series of refreshes to the company’s line of WiFi routers ahead of this fall’s iCloud launch, says “AppleInsider” (http://www.appleinsider.com).

Although Apple’s online store still reflects availability of “AirPort Express Base Station with 802.11n and AirTunes,” authorized resellers like DataVision report that the same model (MB321LL/A) is discontinued. Amazon estimates it will have new stock sometime in the next “2 to 5 weeks,” notes “AppleInsider.”
