I'm considering getting an Iphone 3G in a couple months. But before I make that commitment, I have a few questions: 1. Can I run Safari and a streaming music app like pandora or aol radio at the same time, so i can surf and listen at the same time? 2. Can I edit word or excel docs? If not, can I buy an app that would permit me to do that? 3. I heard the battery wears out quickly when using 3G or Wifi. Is there a portable battery I could get to extend usage time? 4. Is there a website on Safari or an app I can download to view flash videos on Iphone 3g? Non-hacking workaround? 5. Can I listen to streaming music on Edge? Is it great, good, or poor quality? 6. If I see a webpage or document on Iphone 3G, can I hook up the Iphone 3G to a printer w an adapter cable of some sort? Any advice is appreciated!!
