Hi,

So, I know some people have had problems with SSL on PocketPC, I've
finally tracked down the root cause of the problem, which is a normal
pocketPC device doesn't support server certificates that use the SHA-1
Algorithm. Both Verisign and the W2K certificates services use SHA-1,
and this is responsible for the failures.

There's a high encryption pack for PocketPC which adds SHA-1 support,
and installing it has solved all the SSL failures i was seeing.

And the document where i found the SHA-1 issue covered is

c
(see page 6)

And this KB article details how to install additional root CA certs
