BB Curve :: Cannot Attach Files To Email?

Have configured three email accounts on my curve 3g and have been receiving emails and can also send emails from all of them. Can also view attachments such as pdf, xls and doc. The only problem I have is that I cannot attach pdf, xls, or doc files present on my device or media card to any emails. When I go to the attach option in email, only Picture and Contact pop up. Called up service provider (Ideacellular, India) and they told me Blackberry needs to send me attachment services. Called up redington, blackberry support partner in India. After 4 unsuccessful attempts got hold of the supervisor, who told me that " Files cannot be attached to emails on a blackberry". Prevented myself from fainting and told him to check again. He did check again, told me the same thing and has arranged a callback from Blackberry on tuesday. Researched on the internet, found out about blackberry attachment service. Cannot find it on my device. Connected to desktop manager/Applications/ cannot be seen there too! Have downloaded the OS 6 and installed on my comp.
