IDW’s "Terminator Salvation” prequel also is available on the iPhone, with each of the five issues going for 99 cents or the entire graphic novel for just $3.99. Warner Bros. and IDW Publishing present the "Terminator Salvation” graphic novel prequel, which takes readers through a series of events that have transpired since Judgment Day, leading up to "Terminator Salvation”. IDW made its entry onto the iPhone in late 2008 with "Star Trek Archives” and gained even more momentum with "Star Trek: Countdown,” a prequel to the 2009 "Star Trek” movie. Selected "Star Trek” comics from IDW are available via iVerse, which also distributes iPhone comics from Red 5, Image, Archie Comics, Antartic Press, Boom! Studios and others.
