AT&T's coverage is supposed to be moderate in my home area but that makes my iPhone almost unusable inside my house and sometimes outside the house also. I bought a $10 antenna booster from Best Buy which are two think metallic strips. The instructions call for opening the battery compartment and sticking them there near the antenna. I thought I will give that a try on my iPhone but where exactly is the antenna on the iPhone. I do not want to open the iPhone up for this but I want to experiment by pasting the strip somewhere near the antenna location and see if there is any marginal improvement. Any info or experience with such a thing will be very useful to me. Is there any other solution/product I can try? Thanks.
