Additionally, you can download any free comic by Robot Comics, save it to the SD card through the menu, and then open it with Droid Comic Viewer.

Version 1.4 should make finding comics to read much easier.

Are you able to add comics of your own? i have a ton of old comics downloaded onto my laptop like Jonah Hex and Witchblade and was wondering how and if i can import them onto my phone?

Just save them to the SD card (in a folder if you prefer). If your comics are in CBR format this tutorial will help you get the best performance out of Droid Comic Viewer:
