So you want to try to get your on your DROID? Well there is now some good news. Previously you might have been unable to authenticate to your SharePoint portal. This is because the browsers provided did not support the NTLM authentication schema.
FireFox 4 Beta which is now available for the Android platform supports NTLM authentication. So now you can access your SharePoint site!
