Boost Reception on a 3G iPhone
The 3G iPhone may be be a masterpiece of miniature computing, but it shares a similar problem with all other cell phones in that a loss of the cell signal makes calling someone impossible. Boosting the reception on a 3G iPhone can help to improve the signal strength so that a loss of service doesn't occur. Boosting the reception can be done by following a few procedures and will not damage the 3G iPhone in any way.
Instructions
1. Reset the 3G iPhone by holding down the "Home" button on the front and "Sleep" button on the top simultaneously until the Apple logo appears. Release the buttons and wait for the 3G iPhone to reset itself.
2. Select "Settings". Then "General", "Reset", "Reset Network Settings". Press the red "Reset Network Settings" tab that appears and wait as the 3G iPhone resets itself.
3. Push a straightened paper clip into the small hole on the top of the 3G iPhone to release the SIM card tray. Remove the SIM card and dust out the tray with the camel's hair brush. Put the SIM card back into the SIM card tray and reinsert the Sim card tray into the 3G iPhone so that it locks into place.
4. Select "Settings". Then "Network" and turn off Enable 3G in the window that appears. This will force the 3G iPhone to use the 2G network which has a greater coverage and so better signal strength.
