What are you saying the transmitters have unlimited power on a cell tower? They specifically said 2.0 and 2.0.1 has a power management bug that requests way too much transmit power from the tower, on a busy tower that happens to have other 3g iPhone users with 2.0 and 2.0.1 this can cause slowdowns for everyone using 3g regardless of phone and if there are enough the tower will start dropping calls when it hits it's transmit power threshold, which is limited in total watts by the FCC. GSM/edge is not affected since it is whole separate radio system running in parallel with the UTMS/3g on the same tower.

This makes sense from my understanding of UTMS and radio technology in general, and honestly their explaintion seemed much more concrete than your non technical response. If you want to give details of how this is BS please do so.

I'm taking it with a grain of salt, but it would explain quite a bit and certainly doesn't violate the laws of physics or anything.
