Can I stream HD videos through LTE or 4G on my iPhone 5?

When I had Internet at home and connected to Wi-Fi, the HD videos I streamed (Netflix for example) on my iPhone 5 streamed just fine in HD but if I use LTE or 4G they didn't stream in HD, is there a way around this? I have unlimited data through AT&T and I know that AT&T does this on purpose regardless of data plans so phones don't use as much data but I don't have Internet at home right now and I really want to watch HD movies through my iPhone 5 that's connected to my tv through the HDMI adapter.

How to get my music to play through my car speakers with bluetooth?

I have a 2012 Chevy cruze with Bluetooth. My iphone 4s will connect to it fine, and my calls come through perfectly fine and all that, but my music won't play through the speakers without being plugged in to the USB port. Is there anyway I can get it to play via Bluetooth, or do I need to get a new stero system for my car or what? Because its so annoying trying to keep a USB cord in my car and I hate having it hanging out of the console (where the plug in is). My papaw has a Buick Verona with Bluetooth and the touch screen stereo system thing and my phone will connect and play music fine. Mine isn't a touch screen or anything. Just a normal stereo. Is their anyway I can have the touchscreen stereo system installed in my car?

Ok so i currently have a boost mobile phone which is pretty crappy, and I was looking on ebay for a factory unlocked phone probably from at&t or t-mobile because i heard that if they are factory unlocked all i have to do is put a new sim card with my desired network and that's it.
