i heard people were fixing the problem with third party downloads on older versions of the Blackberry is there any way to do it on the 8703 black berry email or msg back

Probably not a great idea to put your e-mail address in a message.

What problem are you having? More accurately, what problem do you believe people are fixing (third party downloads have worked on "older" Blackberrys for years).

What problem are you asking about?
