The GPL requires including a copy of the GPL itself, not just links to it. It's not a hard license to abide by, especially considering the onerous (and downright illegal) proprietary licenses out there. Companies just think that since it's free they don't have to.
Anti,
I was referring to the actual code on the phone not the license itself. Skype is redistributing an appliance and in this case pointing at the manufactures site is the best way to do it.
As to the license, you’re right that skype should make it come with the unit and, were I skype, I would ask the manufacturer to include it..
