My wife has an old analog Motorola cell phone in need of repair.  It is compatible with a hands free booster kit in her car.  I went to the Ameritech cell phone store to get a replacement but they no longer stock the phone.  The personnel at the store couldn't tell me if I had an EE2 or an EE3 model. (The is no such model # on the phone)  Is there any way to find out what model of phone that I need?  Where would I get one if stores no longer stock the model?  Do the newer digital cell phones come with any similar booster kits that steps up the coverage? Please advise.
