Through a cydia tweak or otherwise, is it possible to enable over-the-air mirroring for unsupported-by-default devices, i.e. iPhone 4, iPad 1 et al.?
You would think it's a popular question but all google results result in a dead end. The closest I've come to finding an answer is this topic, where an user claims to have come up with a solution, but then dies*.
Considering people managed to even port Siri for the iPhone 4, I'm sure someone must have made a successful attempt at enabling mirroring, which I guess only involves flipping a switch, i.e. no authorization checks, proxies, and missing binary files here. What I'm trying to say is I'm surprised there's nothing out there.
*or which is more likely, goes offline and refuses to share, whatever - the point is, no solution is given.
