Here's my dilemma: my iPhone 3G screen cracked. It's only one along the left side where the sensors are. But, does anyone know if I can buy a refurbished iPhone 3G for $99 off of AT&T's site? Will they sell me one for that price anyway? My backup plan was just to buy a new glass screen with the digitizer for $30. Which route should I take? Repair it myself, or buy a new phone? -OR- call Apple?
