Will GPS on the iPhone work without a mobile network?

As we know so far, the iPhone 3G will be equipped with a so-called A-GPS receiver. In general, this is a good idea, because assisted GPS enhances the performance of a regular GPS receiver.

But there are sources (Wikipedia, arstechnica) that claim that there are some solutions that won't work at all without being connected to the assistance server. So, will the iPhone's GPS work without a network?

I say: yes, it will! Assuming, the iPhone uses Broadcom's BCM4750 single chip solution, it is very likely it will, because the chip offers an "autonomous" mode that needs "no assistance by network". So, as long as no one messes around on the software backend, the iPhone's GPS should work fine without being connected...
