I may be spending a little karma in saying so, but this is exactly what DRM would be most useful for, when utilized by individuals in their own interest, as opposed to corporations using it to exercise power over individuals. This is exactly where being able to detect if an iPhone is non-jailbroken would be useful.
Or, we can dispense with having DRM on hardware we personally won. How about a protocol for providing a secure bitcoin wallet in the cloud? Basically, everyone runs their own open source mini-OS in their own obfuscated VM (1), which a smartphone app sets up for you and to which a smartphone app only acts as an interface. The wallet information is never on the smartphone, and the DRM is never on your own hardware.
Such an infrastructure would have many other uses, not just bitcoin.
(1) The security of each VM instance would be on an economic basis. Each one might be breakable within a week, say, but the system could be set up in a such a way that the week old information isn't work enough to motivate the effort.
