Griffin's new ClearBoost case promises protection and a cellular signal boost for the iPhone, but does it deliver on those promises? Well, that would depend on who you believe. iLounge claims that the signal boost works, but not under the weakest signal conditions. Crunchgear, on the other hand, called the signal booster "one of the greatest scams perpetrated on mankind since the Kennedy assassination." Hmm...strong words. However, both agreed that the case itself was decent, so at least you have that for your $30. UPDATE: It appears that Crunchgear's review was done using a hacked iPhone on T-Mobile, which would account for the problems. Griffin tells us the ClearBoost was made for AT&T's network.
