I did some GPS tests with Sports Tracker. At the same time I used the HTC HD2 (running Android 4.0.4) and my Nokia N9.

TEST 1
I did a small cycle trip of about 9 km. No clouds and hot 26 °C.
- I kept both devices in my pockets.
- Most of the time I was cycling under trees, so no clear sky above me.
Results:
Distance measured by HTC HD2: 9.28 km
Distance measured by NOKIA N9: 9.47 km
Both devices had problems with GPS reception on the same spots, but the GPS reception on the NOKIA N9 seemed worse. Sometimes the N9 was off by 10 to 15 metres, but most of the time it was 0 to 5 metres for both devices.

TEST 2 (Did this test a couple times with same results)
I drove in car from home to work.
Distance measured by HTC HD2: 2.40 km
Distance measured by NOKIA N9: 2.35 km
NOKIA N9 was spot on. When checking my driving line on the map, it is just perfect.
HTC HD2 was not bad, but it looked as if I was driving drunk on the road, you know what I mean, just no straight lines where it should be. Sometimes the signal was off by 1 or 2 metres.

So, in one test the HD2 is better and in the other test the N9 is better.
Tomorrow morning I'm doing the cycle test with my HTC Desire and the N9 and I'll give you an update.
