I've started developing a full bitcoin App for iPhone (or iPad or iPod Touch)
The App is made from a client that uses JSON-RPC to connect to the bitcoin server/daemon running inside the App.
In the latest release 0.0.13 I have added the option to connect to a remote bitcoin server/daemon.
So you can have your mining machine running in the cloud and connect to it while on the move.
I'm sure I have missed many things a minner needs, but there is a way in the App to enter a manual RPC command line, so I guess it can be useful for anyone.
If your interested, you are welcomed to join the team of testers at
