I recently finally upgraded my old iPhone 3Gs to a new SE. I noticed something weird with it almost immediately. I have an early 2009 MacBook and when I set my iPhone on the lower left side on the keyboard, my MacBook goes into sleep mode. If anyone wants to see this I can get it on video and put it on YouTube. Does anyone else have this issue? The only thing I can think of that would cause this is some sort of radio interference.
