We filing this one under a big ol’ rumor has we have no secondary source to corroborate the information, but there is some preliminary evidence to suggest there may be some truth to it.
We were just tipped off about a new requirement for Windows Phone 8 devices regarding the micro USB port and its placement on the device.
So far, much to the consternation of consumers and 3rd party accessory makers, it has been difficult to make charging stands, car mounts, etc. for Windows Phone due to the haphazard placement of the micro USB port. Some like HTC prefer the side, others like Nokia have it on top and some like Samsung have it on the bottom.
