I am going to have some extra money next month and was looking at buying a few things for my iphone 3g. 1) I've been looking at USB cell phone signal boosters, but I was wondering if any of you have used one? What did you think? I live in a small town and I don't get the best service at my house. I usually have to sit outside to make a decent call. Would this actually help my signal issues? 2) I do quite a bit of driving and I am interested in buying a bluetooth speakerphone device for my car. I am looking for something that is loud, clear and does not echo on the other end. I don't mind paying more if it good quality. I don't care if it streams music over bluetooth. What do you use? Do you like it? I have a 2006 chevy aveo, if it matters. Are there any other must have products, other than screen protectors/cases that you recommend?
