Dear itimpi,

Thank you. That seems likely as a source of the problem, though it does not explain why calibre couldn't detect my old Blackberry either. I suppose it's an analogous problem, or an interconnected problem given that the old Blackberry's sim card is now in the iPhone.

I'll see how things go once the OS4 is available and installed.

All the best,

Alberto Franchese
