Definately - It only gives you 1 cell position (latitude/longitude, is
this the position of the cell tower?), a locality name and an accuracy
measure in meters per API call. This is unlike the Google API where
the whole locating operation can be considered server side and other
attributes such as rxlevel and timing advance can be considered. So
you would have to develop your own application to combine results from
both serving and neighbour cells in a meaningful way (their example
only tells you the serving cell location) and you still would not have
rxlevel/timing advance information.

I look forward to this :)
