Known Wi-Fi networks are predominantly in urban areas. In order to provide your location, data is collected in a form that does not personally identify you. If you do not want such data collected, do not enable the feature. Not enabling the feature will not impact the functionality of your iPod touch.\nTesting conducted by Apple in August 2008 using preproduction hardware and software.

Battery tests are conducted with specific iPod units; actual results may vary. Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced (see www.apple.com/support/ipod/service/battery).
