Hi. I've just bought a Dell Aero smartphone. There is a little problem with it - when I try to edit contacts that are on my SIM card, I get the error described above. Everything works perfectly when I edit contacts that are on the phone itself. Btw, when I try to copy a contact from phone to SIM I also get the notification that some info may not be copied due to "the limitations of the SIM" so i'm guessing the problem may be related to that as well. Anyway, id really appreciate if someone could help me out with this, as I prefer to keep contacts on my SIM.
