This should be stickied, or better yet, a wiki
so that people can update it freely.
Another interesting permission that should be mentioned is "read phone state and identity
" (required, for example, by the Speedtest.net application). This sounds like the app can read your phone number or IMEI. Some
say the permission
that important, while other reports indicate that your IMEI can indeed be read - Locale leaks your IMEI
, and the most likely permissions required by Locale to do that are "read phone state and identity" and "modify global system settings".
