I hacked my iphone from the UK yesterday, with the thread on this forum, worked fine btw!
But, something is not working fine. When i open iPod or Safari, i see the screen for about half a second in portait, and then it automatically tilts to landscape. And with moving the iphone i can't get it back.
Could this be anything software, or is it definately hardware, a broken accelerometer?

And if it is... did anyone with a hacked iPhone try to get it replaced? Have to go back from Amsterdam (Netherlands) to London then...

Thanks for answering!

Never mind, it worked after a nights rest. Weird.
