Mobile Entrée is great right out of the box
I can confirm that the following statement is 100% true.
" an innovative and easy to use SharePoint mobile experience ... with no custom development, client-side code or separate server requirements."
Within a very short period of time, I have enabled our users to access the Sharepoint sites on Blackberries and iPhones.
The technical support is more than wonderful. They response to my emails quickly and they even spotted out mistakes in our Sharepoint Server configuration.
Highly recommend the product and the organization.
