Greetings!
Dear tell me how internet speed is required for Updating To Wp10?
Please inform me all requirements.
Free memory space,
everything
there's no minimum requirement for the internet speed, since the upgrade donesn't start until the whole update package is downloaded and checked. you can download it even on 2G/EDGE i think, it's just going to take forever that way
about the storage, i remember that when i installed the w10 preview on my lumia the phone asked for 1.7GB free space in the internal memory, so if you can free let's say 2GB it's going to be enough; we don't know yet how much the stable w10 update is going to take though, since it's still in developement
