Microsoft Windows Phone 8 released

Completing the upcoming Windows assault starting line-up alongside Surface, the eighth iteration of MS's phone OS bring integrated Skype calls, more dynamic homescreen tiles and the NFC-enabled Wallet Hub to challenge iOS and Android.

Expect a fleet of new, higher-specced devices to coincide with the launch, too, not least because Windows Phone 7 handsets will not be upgradable to the system.
