It seems that an eagle eyed person actually managed to catch hold of a Nokia Lumia 900 smartphone which was sold over in Finland, where this particular model actually carried the Windows Phone 7.5 Tango operating system on-board? This particular update is a minor one though, and is also one which Lumia 710 and Lumia 800 owners have been waiting for for quite some time already. Apart from Wi-Fi sharing and tethering capabilities that will be enabled by default on the Tango update, there are also other performance improvements made.
Here are some of the details concerning the Tango-powered Nokia Lumia 900 which was caught – it had an OS Version of 7.10.8773.98, while the firmware revision number stood at 2175.1601.8773.12141, with the hardware revision number being held at 112.1914.2.0. As for the radio software version, it was 2.1.75.16, while the bootloader version stood at 7.17.2.0. The chip SOC version was 0.85.2.1, and that is about all we know so far.
