Today my phone crashed and I was reminded to do this so I can upgrade the OS on it finally.
There's a few utilities out there that will do it. I tried one that only showed 190 points (out of the 12452 that I have). Then I tried iPhoneTrackerWin which at least worked. How cool is this!
But it didn't have any sort of export (apart from a log).
So then I tried nphonetrack which outputs a raw csv and a kml file you can load into Google Earth.
Here's a few more from iPhoneTrackerWin
Canberra.. have ranged all over here!
Syd-uh-nee!
Visiting Chay and David last year
Jordan didn't rate a mention
Heathrow, Leavesden Studios and Windsor feature in addition to London
Some weird stuff happened in Japan. Sapporo and central Hokkaido didn't rate a mention, yet there was a stack of stuff around Sendai. Maybe it transposed some stuff for a while?
