I like having a charm on my phone, it gives me something to play with when I'm bored and something to "accidentally" smack people with when they're being annoying.
I'm gonna get one for my iPhone just to mess with people.
No one NEEDS a handset for their cell phone. But they do need it if it's Hello Kitty themed.
Careful, this might make your phone a little too delicious.
If I MUST make a call on a public phone, it better be this one.
