Unbreakable phone

That's super. It's not the phones title though. Add onto the fact Bob there challenged him to try and break it and he did. And it all adds up nicely.

Well, with the right degree of pressure or with the right tool, anything is essentially breakable. It does seem pointless to have a phone be like that, though. Are you planning on using the phone as a hammer if you can't find one handy? That'd be pretty fun, but I'd probably just go and buy a hammer if I wanted to do something requiring a hammer rather than using a phone. Stick to the purpose of the phone and don't expect much more of it besides being able to be dropped a couple times and still work.
