This happened to us this week.
Wednesday, I flipped my old phone open, and, well, it kept going. Hinge just shattered. So Wednesday night we ended up shopping for new phones (since we were both outside of contract anyway). My number (for those of you who have it) hasn’t changed, but now my phone plays music too.
And when I added Xingtone to my computer, well, let’s just say I have some very interesting ring tones now :)
