A:AnswerI recently purchased the same tablet and it in fact came with the USB/power cable and the wall adapter. I would contact the Best Buy store you bought it from or even contact Asus.
A:AnswerYou can download any apps from the Google Play Store and there is no iTunes app, but you can definitely still use ITunes if you look it up in your browser. You can download a few movies given you only have 8 GB.
A:AnswerI don't think so.. You would probably have to get a tablet from your carrier if you want to use it as a phone. There is apps in the Google Play store that you can use for free texting and maybe some apps you can use to make calls. My son does it all the time. That's how I know!
