It's better, but is "JON202555" $2.99 a month better?
No, but perhaps something like iMessage is better. No fee and it's also an email address. Seems more useful.
You can use iMessage with email addresses.
... I know. That's why I'm suggesting it's better than Sprint's new thing.
Guys - your should really try CallmyName app.
It gives a much more comprehensive solution - it includes phone number, email, address, skype ID, Twitter, FB, picture, etc
And most of all it is absolutely FREE...
