I think the Xperia 5.1 update is coming in a 410.5 Mb / 10.7.A.0.219
It is absotutely true, it has updated to ICS. The terminal is a company-free one. I don't need to lie. Check out the file.
Still haven't found any solution. Seems that few people are suffering from this issue since there isn't any information in the internet. Please help.
Spain. Company free cell. I got the message ten minutes ago, still didn´t updated. 375,80 MB I don't have WiFi nearby.
