On iPad or iPhone, I take a snapshot of the screen looking at the screen sideway (Landscape mode), but the snapshot is taken to be in Portrait mode? So if I send this photo to a friend or post it on Facebook, it will be 90 degree off... 

(I mean taking a snapshot by pressing the Power and Menu button at the same time)

Any fix or hack to make it work better? (this also looks like a bug that might be able to go into future release of iOS)

I can upload it to the computer and use the computer to turn it 90 degree... but what if there isn't a computer around?
