Wrong ZoomToSpan for Latitude

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Call ZoomToSpan with Lat, Lon, where Lat > Lon

What is the expected output? What do you see instead?
Expecting to get the right zoom level, getting a wrong one instead. 

What version of the product are you using? On what operating system?
Using osmdroid 3.0.1,

Please provide any additional information below.

Probably: 
  wrongLevel = rightLevel - 2 on normal screen devices

and
  wrongLevel = rightLevel - 1 on small screen devices

Please retest and let us know if you are still seeing these results. We have 
recently switched algorithms.

The latest release jar has the new algorithms.

I've tested 3.0.3-jar in emulator (WVGA800, Android 2.2)

I called zoomToSpan(10000, 10);

So i'm waiting for bounding box, where delta_lat ~ 10000, but i'm getting 
following values.
lat_north = 49500297
lat_south = 49459923
delta_lat = 40374

I don't have a device now (or better to say, no datacable). But tomorrow i'll 
send you results.

Are u sure new algorithms are within 3.0.3?
