"use this app to shorten your iPhone battery lifespan"
20 November 2009
Pros: if the app uses online map or updates its map daily via data, that would be the only good thing. I choose Garmin anyday over TomTom myself.
Cons: (assuming that the car kit would charge the iPhone when it's hooked up, pretty sure that's the case) I was told that charging a cell phone in ur car is a very bad for its battery, as voltage flow changes constantly from the state of ur veh operation.
