I updated last night and did a quick test - when it ran, the GPS couldn't get a lock (this has never happened to me before, I was at home with AGPS enabled, always locks in < 5 seconds).

I just retried it now & still no GPS fix - I tried ovi maps, no joy there either. I changed the AGPS server from supl.google.com to (the original) supl.nokia.com, but that didn't help. I then rebooted the phone, which fixed the problem (both modrana & ovi now work again). Probably just a random glitch unrelated to the modrana upgrade, but thought I'd mention it in case others also got the same issue.
