VERY basic iPhone questions here. I already own a mac computer, but currently use Blackberry for phone and email. It works great. However I like the idea of eliminating one of the devices I have to carry. The iPod. So I could have my phone and iPod in one device, sweet. Anyway, here are my questions. 1. If I buy music on my iPhone 3g, and then plug my iPhone into my Mac, will the music I bought on the phone, be uploaded into my Mac's iTunes library? Or are they strictly for the iPhone only? 2. No landscape mode for sms? No mms? No video? Are these things coming in a future update? 3. I get on an airplane or I'm killing time and I want to turn off all the phone functions, except iPod and movie watching, to conserve battery. Is this possible to do? Sorry for the basic questions but I have very limited experience with iPhones.
