Enchanced Full Rate will give you much better sound quality when you enable it. The new Enhanced Full Rate CODEC adopted by GSM uses the ASELP (AlgebraicCode Excitation Linear Prediction) compression technology. This technology allows for much great voice quality in the same number of bits as the older Full Rate CODEC. The older technology was called LPC-RPE (Linear Prediction Coding with Regular Pulse Excitation). Both operate at 13 kilobits.(but you take up more space on the network, so they can charge you more) - Talk-time is reduced with about 5%

Nokia Speed Trap Detector Urban Legend spread by Nokia Engineers ;^)

Unfortunately only Nokia phones have this function. The Cell Phone info display needs to be de-activated. Settings -> Phone Settings -> Cell Info display. Each time you turn off your phone, or even each time you loose contact with your carrier, you'll have to activate it again... It is done using steps 1 through 5 above, but the number (00000) will be already on the field as a default.
