iOS - Older models and software
Pebble is optimized for iPhone 4S and above.
Older iPhone or other iOS devices will have limits to the notifications they may receive. Our current iOS mobile app relies upon Bluetooth LE capabilities that iPhone generations before the 4S do not have the ability to support. Earlier versions will still be able to receive basic notifications (SMS, email, phone calls) and you'll be able to use your Pebble for fitness apps and music control. However, you will not be able to take advantage of our 2.0 app or firmware.
