A custom, corporate typeface, named 'Verona', by Miles Newlyn..
As seen on Typophile..

( Edit.: For rather similar, publicy available, alternate typefaces, refer to 'Melior' and 'Renault'.. )

thank you for the response, David!

Yves, I do apologise for obviously posting a font that has already been discussed in-depth on typophile. In fact, before posting I searched the archives with all kind of different terms ("3G", "hutchinson", "3 mobile", etc.) but to no avail.

Once I got the name, Verona, it was very easy to trace it down.

Thanks and have a nice day!
