Could you point me to the points producing that weird effect and/or to a web site where I may submit my points and have them drawn on a map without having to mangle with the iOS app?

I checked the first one
2012-06-29 17:16:27.947 inArrivo[6293:707] 41.702019, 12.345350

which also appears slightly further down:
2012-06-29 17:16:27.977 inArrivo[6293:707] 41.702019, 12.345350

so it's definitely the data. You could try and find a duplicate of
every row like I did, but that might take some time. It's probably the
only way though: can you load the points into a database to help you?

I don't know of a site where you can submit a list of points though,
other than one where they are encoded first, which isn't going to help
find duplicate points.
