which cell phone has the loudest and clearest speaker. Interested in finding out as one of your hub topics? I just joined an MLM that sells hands-free service so you can drive and talk on your phone (hands-free) safely and conveniently. I usually use a bluetooth on my ear when I am driving but I forgot it today and still wanted to talk from my cell phone (legally) while driving I put my iphone on a sticky on my dashboard and talked while the phone was there, not in my hand. That way I could have my hands on the wheel my eyes on the road while driving. The sound only seemed fair to me.
