The bluetooth stack on iOS isn't terribly stable. I used to blame the Pebble for it's disconnects until I discovered that it corresponds with the whole stack going out. I've never had a problem with my phone locking up and neither has my wife but some people seem to have constant problems and some none at all. Bluetooth has never struck me as a particularly stable technology in general. Pebble has been working on going full Bluetooth LE and dropping the regular Bluetooth connection. I'm not sure what the progress is on this (or if they abandoned it) but it would probably improve stability and battery life.
