iPhone case makers "leak" some iPhone 3G specs

It seems that some iPhone accessory makers have been working off of reference designs, shown here, that describe some sort of new iPhone. While no one is sure if this is the 3G model, the level of detail is fairly compelling — excelt for the image of the bottom with no speaker holes. Remember that case makers thrive on be able to launch product as soon as the device is available, which means they’re throwing all sorts of intelligence gathering at this right now. Here’s hoping.
