Agreed, but try not to think as much as a software engineer and think as a simple user. Some people just forget their number - and it's useful if they can see it on the mobile, for telling other people. Some people carry a few SIMs around, and this information - the phone number - is useful to them. It might be that regular mobile phones use some kind of workaround to get this information - like, say, getting the destination number when they get a call - but nevertheless it is useful information that can be show to the user. So, really, no way to get it from the OS data? Best regards, -- Cláudio "Patola" Sampaio IRC: ptl - Yahoo: patolaaa Campinas, SP - Brazil.
