Wow. That's great. I was repeatedly told by others that AGPS required the cell network.
However, a quick look at Wikipedia looks like this isn't always the case: http://en.wikipedia.org/wiki/AGPS Apparently, some AGPS units work as you say, but some seem to always require a connection to the assistance server, or they won't operate. Not sure how you can tell which type of AGPS you're using.

The almanac tells the GPS receiver where in the sky to look for the satellites. It gives you faster acquisition time. If you do not download the almanac with the computer and transmit it to the receiver you will only lose the super fast time to first fix. Most of the new receivers can get a fix in 35 seconds and this is without using their agps data. The i-blue 737A+ is an example of a receiver that uses agps.
