Well, mine was hacked, losing 1 bitcoin. USE TWO FACTOR AUTHENTICATION!
what happens if you loose your mobile, what happens to2 factor then?
If you're smart you'll have written down your 5 - 10 throwaway two factor authentication codes that you get when you signup for 2FA with Gmail and you'll use one of those to log into your account to turn off 2FA and change your password and reset everything.
Just my opinion but if you have a lot invested in Bitcoins/ALT currencies I'd have a separate phone locked in a safe so you don't lose it.
