Anyone knows an algorithm for rotating a bitmap in Compact Framework?
Please advice.
(One possibility is to use SetPixel() and GetPixel() but these are
increadably slow).

A search via GoogleGroups, groups.google.com, of this group,
microsoft.public.dotnet.framework.compactframework will find you a number of
old threads on this topic.

See my example here:

For CF2.0 you can use LockBits and use the same technique like shown in
my sample.
