Coinbase releases iPhone app

I'd hope that in this day and age every native app, especially those of a banking nature, is using HTTPS where appropriate but (without sniffing your own network) there is no way to tell.
"Can't actually send money from this app"
"I can't add funds or send anything."

Edit: I know they've redacted apps after release plenty of times in the past, but it clearly involves bitcoin and they clearly have a stance on that, so chances are good that it was a calculated decision.
Their hot-wallet dependency and my storage of coins at a central location simply does not give me enough assurance my coins will be safe there for a significant amount of time.
Bitcoin, unlike other currencies are irreversible. You have one, and only one chance to keep them safe.
I rather be content with the loss of Bitcoins in my possession, _knowing it was my fault_, than losing them to a thief holding Coinbase's staff at gunpoint for the offline wallet's private keys.
