We recently reported that attaching a small piece of scotch tape to the outer side of the iPhone’s SIM card (the side that does not have metal contacts) or the inside of the SIM slot (again, on the contact-less side) can provide a surprisingly dramatic boost in signal strength. Despite the naysayers, several readers have […]
