v2.5.1 and v2.5.2 are identical. I had to increment the version number to satisfy Maemo Extras Builder, and I forgot to update the version in one place in the code. So, you may see a sprinkling of 2.5.1 vs. 2.5.2, but they're the same version, so no worries.

As for your N810 GPS issue: is anyone else experiencing this problem? Are you able to use Nokia's Maps application without issue?
