Does any one know if and how you can access a webDav drive with the p900?
Accessing webDav (iDisk)
Simple: 😉
Plan A:
Find your favourite P900 Software Development Kit. See http://developer.sonyericsson.com/
If required, port or write a P900/SymbianOS version of a HTTP protocol stack that you can use. Specs here: http://www.w3.org/Protocols/
Port or write a DAV client/library/service that uses above HTTP stack. See RFCs 3744, 3648, 3253, 2518, 2291, etc.: http://www.ietf.org/
Write an actual client application that uses above to access your data.
Consult with Apple, if appropriate/required.
Plan B:
Find someone else to do it for you for free.
Plan C:
Pay someone to do it for you.
