Dirty hack to boost cell phone reception

Took a look at my aging Motorola V3i and realized that there is a rubber lid on the back of the phone which i found odd. After checking it out on Google, I found out that most phones have it and when removed, it is a point for an external antenna. I embarked on creating a makeshift external cell antenna for next to nothing. It would come in handy when needed.

Items needed:
1) Insulated wire
2) Wire Cutters
3) Ruler
4) Skewer

                 1. Cut out 20cm of wire

                      2. Measure out 5cm of wire and bend it to a 90                                        degree angle

                      3. From the bending point, wrap 5 times on the skewer

                      4. Pull the wire out

                      5. Measure and bend 2cm from the end

                      6. Remove the insulation

                      7. Your makeshift cell antenna is ready

                      8. Remove the rubber lid

                      9. Insert the end of the makeshift antenna to the antenna                        jack

                      10. Antenna mounted

                      11. Signal before mounting the antenna

                      12. Signal boost after mounting the antenna

be sure to not touch the wire with the "ground" into the little hole, there's a little copper donut or some kind of circle and a pin inside of it you must touch only the pin (the ground is the donut), if you touch both you will damage your phone

I experienced a similar problem. When I bought my iPhone, I first checked with “Got Reception?” ( It’s a great resource for finding out where reception problems are most likely to occur BEFORE you lock yourself with a specific carrier.
