I have nokia lumia 900 as well.
OS is 7.10.8858.136
firmware - 2175.2307.8858.12480
I am able to download both bluetooth sharing and ringtone maker.
Ringtone maker is working but Bluetooth Sharing is still saying I need to update my device. Please suggest what to do.
Hi all, yep had update notification on my unbranded Lumia 900 first thing this morning, connected to zune and received over two updates what I assume is the revised 7.8 firmware ( os version now 7.10.8862.144, Firmware revision no 2175.2905.8853.12440, Hardware revision no 112.1914.2.0 ). I have Ringtone maker and Bluetooth share installed & so far both work fine
