I was having some issues with WiFi on my iPhone. Drove down to Apple Store. They replaced my phone, drove back home and synced it with my 3 week old MacBook; it wouldn't connect the phone. So I drove back down to Apple store and told them that the iPhone wasn't working. Genius tested it and turns out the USB port on my MacBook wasn't working. Ended up getting the MacBook replaced. So basically got a new MacBook and a new iPhone! Pretty productive day lol.
