I have an HTC Hero and I was wanting to use it as a portable video/music player and storage device for files. When I went to open Astro recently it says it is expired, then says "Continue in seconds" there is not number in that sentence, just continue in seconds. Is there any way to view files on the sd card without using Astro? Keep in mind I do not have access to the market on this phone, I am not with Sprint anymore.
