Is there any way to use my developer account for SFDC on Database.com?

Is there any way to view an object's attachments on a mobile device?  I would like to see documents that have been attached to an Opportunity on my Blackberry.

I am trying to use Apex Explorer and when I try to login, I am getting an error.  The error message window is titled "Partner Sample" and the message is "Login failed: Input string was not in a correct format."  

Any ideas on what to try?

Hi,

I have installed WAMP server on my laptop and deployed HTML5 application from Salesforce.com for Mobile workbook.

App location: 

C:\wamp\www\HTML5

Modified Login.js:

var clientId    = 'valid client key';

var redirectUri = 'http://localhost/HTML5/oauthcallback.html';

var proxyUrl    = 'http://localhost/HTML5/proxy.php?mode=native'; 

Problem:

========

After successful login I am not able to load the application. I am seeing spinning wheel "loading" .

Could someone help me. 

Thanks,

Rag
