I've recently picked up again on reading Dr. Trent Oakes' blog. He has his PhD and is a researcher at Standford. He's an absolutely brilliant guy. He understands all things having to do with the intricatery of cell phone circuitry. I recommend you check out his blog: iamfullyintegrated.blogspot.com
He also has a twitter account and he can be found by the name Trent Oakes.
I really recommend reading his posts. They're odd and strangely fascinating at the same time.
