answer:The iPhone should have a sensor by the ear piece that detects if your head is by the phone. Once you bring the phone up to your ear, the screen should automatically turn off so you can’t accidentally press any of the keys on the screen. For phones that sync to your mac, the new iPhone is probably your best option so far. Unfortunately, it’s sold out everywhere right now and you’ll have to wait until the beginning to mid July. I would pass on the 3GS model since the iPhone 4 has so many newer features and is definitely worth the extra $100. The Blackberry lineup is probably your best bet IF you don’t like touch screens, the Bold or the Tour are excellent options. Blackberry has its own software for Mac to sync your contacts, music, and other media. It works pretty well. Finally, you have the Android option. Currently, Sprint’s HTC Evo 4G is the best Android phone on the market. If you wan’t Verizon, I would hold out until July for the new Droid X. (T-mobile and AT&T don’t really have great Android phones at the moment.) Android doesn’t have a native software to sync media, but Double Twist works perfectly, and is a lot better than drag and drop for media management. Android can sync your Google contacts and calendar. If you have your contacts and calendar on Address Book and iCal, you can set those up to sync with your Google Account. Let me know if you have any other questions.
