GV Mobile + used to be only on Cydia on the iPhone, and Apple, on Motzei Yom Kippur, approved it. It was $3, but was free until midnight Motzei Shabbos Chol Hamoed. Then, as claimed on the author's web site, there were errors on the Apple servers, so he's pushing his free promotion until noon Sunday Chol Hamoed! Grab it now, even if you currently don't have an iPhone/iTouch! You are able to download it and its updates free later!
