I like it - it's software the encourages you, maybe even forces you, to share the experience with someone else turning every user into evangelist. It also seems like it would make financial transactions very simple.
My only concern would be that phone numbers still haven't become non-transferable identification.
I'm sure you have considered these issues before but I would wonder about:
My parent dies and their cell phone account is turned off - how do I get their money out of this service?
My wife and I share a cell phone but we don't share checking accounts.
Someone has already created an account for my phone number.
