Pay careful attention to what they say about CDMA phones and amplifiers, the way I read it, with CDMA phones (Verizon, Sprint, Bell Mobility and others) you only get amplification from the antenna. I may have misinterpeted what they say, but I would check out the performance with CDMA no matter what brand of amplifier you choose. There are some phone experts on the Forum who may be able to give a better response than mine, but be careful before you spend the dollars.
On edit: I just took another look at this site, and it has changed somewhat, but still read the FAQs and try to make sure that what you buy is actually going to work in your situation. It is not as simple as if seems.
