Firstly, have u checked to make sure that when you installed your OS you added Blackberry attachment service. Also, when installing your OS there should be an option to add Docs to Go. This is a free program for Storm users and opens word docs, excel and powerpoint.
As for jpeg and pdf your phone will be open to these if you installed the blackberry attachment service. To check to see if u did go to options - advanced options - applications. Blackberry attachment service should be listed there right under system software.
Unable to View Attachments: "The attachment type cannot be viewed on your phone."
Please read completely before performing the following procedures. This has resolved the issue for several members. (second step is the clincher).
On your device do: options>advanced options>applications>look for Blackberry Attachment Services (should be near top of list)>highlight it,>Blackberry button>edit default permissions >User Data> and set to "Allow" in the User Data section. Expand that User Data section and be certain everything is "Allow". Then BB button > save.
Pull battery, reboot and give it a go.
(note: If your settings did not require any change, no need to perform battery pull. Go to step 2 which completes with the battery pull and reboot).
Send your service books. (email settings>BB button>service books>send service books)
Upon confirmation, pull battery, reboot.
Important Note: Please send yourself a NEW email with the appropriate attachment type(s) after you have executed the above steps in order to confirm you are now able to view attachments. The attachments that you received prior to performing these steps may still gave give the error message when you try to view them. But all attachments received after the above "fix" should be viewable without any problems.
You should be good to go.
Hope this works for you.
