Today I learned how to put contact info on my new blackberry so that it shows even when my phone is (company required) password protected and Contacts are not accessible. For someone who loses things at a heart-breaking rate, this kind of thing is important to me!
Settings > Owner > [edit to add how someone could reach you if you lost your cell phone]
Thanks to Barbara, who found out that I could do this at all!
What useful thing have you learned?
