I have nokia lumia 800 with the product code 059M405.
I look the new update is available for my device but zune can't find the update.
what is the problem
Please see this post for information on the update procedure.
Press the 'Accept As Solution' icon if I have solved your problem, click on the Star Icon below if my advice has helped you!
Also bear in mind that Zune only checks for update availability once every 24 hours, so for two UK devices running 059L7C2 one updated yesterday and the other today!
