Hello there jon6er.
Thanks for joining us here at Android Forums.
You've come to the right place to learn more about your Epic 4G Touch. The folks that in that phone's section, that Digital Controller linked you to, should be able to help with any questions you have on it.
Of course there's much more here at AF, so take a look around, and if you have any questions, please feel free to ask. We'd be happy to help.
Enjoy your time here at AF, and happy posting!
