sybase unwired platform iphone development

Hi all,

A sharepoint connectivity is established using SUP and necessary code for iPhone is generated. Our requirement is to login to sharepoint from iPhone application and download / sync a few documents present. If it is possible, please suggest us the approach.

when there are documents added [for a particular user] in the sharepoint server, a PUSH notification is issued via SUP server to iPhone. If it is possible, please point us to right person or sample code.

we need to develop this using sybase unwired platform.
any ideas welcome

thanks in advance
