subject: Double your iPhone 4 battery life with the MiLi Powerspring [print this page] I'm wondering whether this case also serves a third purpose. As well as the extra battery life and added protection for your phone, does this not also help with the antenna problem? The casing means your fingers won't be touching the problemtaic area of the iPhone, so it may solve the signal drop issue.
