Well, Internal GPS (not AGPS) seems taking HUGE amount of time for initial sync (10min is not enough in my area). If you do it or do it via AGPS then it works fine on PR1.3.1 or PR1.3 ... until next day - I still have an old PR1.3 image on my N900 and I am able to test it.

I have no idea then it stopped working and it may be just increased RF noise or whatever.

Now - after installing PR1.3.1 I lost EXTERNAL GPS capability. It blinks forever but doesn't get it from my Holux240. And old image (PR1.3 or earlier) does WORK fine and fast in this case. Unfortunately, it takes time to confirm this because after initial hook with satellites it works fine ... again, until next day.

I rolled back libmaemosec* packages but it doesn't help - external GPS capability is lost for initial hookup - something other corrupts it. And I will setup the pretty same environment for my tests (WiFi/Cell) but all it takes time to test.
