Which side is the GPS antenna on?

If the antenna is small, on one side, and at the back, then running the phone in landscape with the aerial side facing up is bound to have the best chance of "seeing" the sky. Without knowing which side is "up" for the aerial, we have a 50/50 chance of getting it right or wrong.

So do you know which side it is on, and therefore whether we are better having landscape with the buttons to the right, or landscape with the buttons to the left?

Also does firmware version make a difference (other than the default config of these settings)? Or in other words, would all firmware versions have similar performance if set to these recommended settings, or do some firmware versions have better drivers or sensitivity too as well as different settings?

Thanks for the excellent info!
