Android/BlackBerry: SleepRinger mutes all phone calls and text messages except for those from contacts you have whitelisted; sleep easy knowing that the people who need to reach you can do so.
It’s that simple to use–install the application and just start adding contacts to your whitelist. You can specify if SleepRinger should allow calls, SMS, or both and whether it should ring or vibrate. Even if the phone is set to silent the numbers in the whitelist will ring through correctly.
SleepRinger is a free application, Android/Blackberry only.
