1. Will photos be resized by iTunes to make them show up better on a retina display or will the same photo cache be used? Someone with an iPhone 4 may know. 2. How are people in facetime or any other app that uses the microphone be able to hear the user when the microphone is on the back of the device? Speak loudly? 3. The speaker now has a hole on the bottom left of the device. So does that mean the sound is going to be muffled when it's covered? 4. The iPod Touches always seem to be slightly faster than the iPhone released months before. Will this 4th generation iPod touch be faster than the iPhone 4? It's the same chip from Apple, so I was thinking not. 5. Do I need to keep a piece of duct tape on the front camera to keep Apple from spying on me?
