Questions about Username

[Timespansoul]

Hi again,

when I installed Touch I was prompted to enter a Device name or Username, I can't remember now. I do remember that the keyboard didn't pop up so I couldn't enter a name. I'm not sure if I'm remembering this correctly, it said I could change it later.

Is it expected that you can't input a name?
Is it also expected that you can't change the name?

Can someone verify if the setup states that it can be changed later?

Thanks,

Time
