I've also been wanting to try the HDR feature, but I don't want to lose my Jailbreak. Is there really going to be a jailbreak for 4.1? I'd think it would make more sense to wait for 4.2.
And I have ProHDR, but it's too slow, and you don't save the original, so whereas on Apple's implementation you can just casually use the camera and still get the HDR benefit if it improves the photo, you have to consciously make a decision of whether the scene will benefit from HDR and whether you are willing to trade-off a potentially slightly better photo for the time it takes to take shots when using ProHDR
