To provide more accurate location, instead of using GPS (that offers bad accuracy).
And to get rid of their dependency on skyhook.

GPS and bad accuracy? Have you actually any idea how AGPS works?
They need it to increase the location acquisition speed, not accuracy. Civilian GPS offers 4m of accuracy(or something), while AGPS may start with 1.5km accuracy and narrow it down as more GPS satellite data is received.
In fact, with that data you don't even need GPS to establish your approximate location.
