Better description of permissions Is there a list of permissions with more detailed descriptions available? The standard ones doesn't feel good, and I don't trust developers who write that they need permission X only to do Y--if their app requires permission X, this app will be able to do anything permitted by X, not only Y.

For example READ_PHONE_STATE is described as "Allows read only access to phone state" -- but what is included in that phone state? Is it only connected/disconnected? Or maybe it includes phone number I am actually talking to?
I can't find a good complete list, but you can always search for the permission on developer.android.com.  In the case of READ_PHONE_STATE, it does look like the phone number can be read.
