Compass not so accurate???
Hello guys... Just a clarification if I'm wrong but when you hold your iphone 3gs at a 90 degree angle (standing up) and then lay it flat on a table pointing at the same direction... Wouldn't you get the exact same reading in the digital compass.... I get two diferent readings....
I read the compass works regardless of how the phone is held in your hand....

it takes interference poorly. get it near any speakers or other magnetic source (microwaves, some televisions, computers) and you'll see what I mean. I can hardly use it at my desk at work because of multiple speakers
it also doesn't like not being perfectly level. I can wobble my hand up and down and the compass changes its direction. (to be fair real compasses hate not being level either)
digital compases will never be the same as a manual compass and even manual compases wobble in the same way. I've seen a compass move between 5-10 degrees if I move my hand. It's just a lot easier to see when there's a physical needle.
Something tells me most of the inaccuracy is from people not holding it level.
