It may even improve the signal of the iPhone 4 at the same timeJust make a little aluminum foil hat for your phone and it should be fine![]()
If you didn't know, even if the phone is "turned off" and the battery is still in it, it still sends a little signal all the time. The only sure method to avoid tracking is to take the battery out of the cell phone.This is one reason that I always turn my cell phone off when I leave home, because all (recently built) cell phones has GPS tracking devices built in. Only when I need it, I turn it on.
"An RFID tag was scanned at a distance of 69 feet, and that was back in 2005, the possible reading distance now is probably much greater than that."RFID tags are also only good out to about 2 feet. Useless for tracking purposes.
