This new ClearBoost case from Griffin, has a built-in booster antenna that enhance the wireless signal and sends it to the iPhone internal antenna, so you can get a better wifi connection to enlarge service areas, surf the net and get emails via your handset. In addition, it provides hard-shell protection for the iPhone, keeping it unscratched from top to bottom. Mind you, recent reviews state that the “signal boost works only under certain conditions” and “does not appear to improve iPhone performance under weakest signal conditions“. However, in some cases, the ClearBoost “deliverimproved cellular antenna performance…” and “can help stabilize shaky data and cell phone audio conditions when iPhone is in 2-3 bar range“. In any case, the Griffin ClearBoost is a worth trying accessory, priced at merely $35.
