You would think this is planned, but there is no way that the FCC is efficient enough to release documents detailing the iPhone 3G S on the same day as the announcement. No way. But here they are anyway.
So, if you need to kill some serious time, head on over to the FCC and browse through the pages and pages of patent documentation. There is everything in there except for external photos and the retail manual for both the 16GB and 32GB iPhone 3G S. Enjoy!
