I typically encounter this when attempting to run one of my apps from my Eclipse development environment when I've already installed the signed and exported APK on the device (or vice-versa). As others have said, the solution is to uninstall the old one first. – stephendnicholas May 17 '12 at 15:55

You must first uninstall the application (that has the old signature) -- and, then, install the one with the new signature.
Note: actually, this is one of the reason why there is a security system like these signatures: it makes sure no user will think he's updating an application, when he is actually replacing it by another one, possibly fake (as, in theory, only the real original author has the ability to sign with his own signature)
