Dear iOS gurus, Unfortunately my iPhone vibration is not working correctly, sometimes when i set the phone in vibration mode (at work) it does not vibrate. So, i would like to activate a time or location based ringtone. When i am at work i would like the ringtone to be set at level 2 when i am not at work at maximum powa! Do know if i can do this in iOS or if i need an app for this? My phone is not jailbraked and i am not planning to do it, any other solution? Thank you in advance for sharing your guruness. Spiet.
