I haven't tried the iPhone version - but the N95 version is similar (which I found rather good) with just Cell positioning. I imagine there may be some limits on whether multiple cell towers can be seen with strengths. Worst case it would put you *at* the location of the cell tower you are connected to.
Would be interested to know what type of filtering algorithms they're using to get an estimate from so many 'sensor' measurements of varying accuracy. One major problem with the N95 GoogleMaps app is that it locks up if you lose data connection. Anyone else experienced this on the iPhone or N95?
