A few minutes ago, a new SkyDrive has gone live!
If you are a current SkyDrive customer, all you need to know is in this picture. To see this offer, you have to log in twice!
SkyDrive 7 GB to 25 GB upgrade fr current customers - act now!
But: It seems to work only for accounts where at least one file was uploaded before the change. 
You can also download a new SkyDrive application for Windows here.
i have no any button “Free upgrade”!! what’s going on? o.O
You must log in twice!
i have button but only for the other plans
Log in again, you will see it for the second time!
i can see! but in my other accounts i can’t do it because i have zero files in Skydrive u.u, thanks anyway!
I uploaded first files in February 2012. But still I am unable to get more than 7GB. I’ve relogged about 20 times …
