Location cache in android ICS?

My understanding is that in gingerbread and lower, android stores a cache of 200 fixed locations and 50 cell location corrections. They were saved in cache.wifi and cache.cell files in /data/data/com.google.android.location/files, and root devices can view these locations using applications such as.

However, these types of applications no longer work on ICS devices. Does this mean that android no longer caches cell / wifi location fixes? Or does it just mean that no one was able to create a similar type of application for ICS or no one can determine where the cache is stored more?

Assuming the cache is stored locally on the device, then when the network location is requested, is this the location returned by the android received through the local cache or is it new from the network? How to find out if its new or from cache?

Finally, how much network data does the network locations provide (with wireless connection on / on and data connection turned on)?
