Let me start by saying I love the I4. Upgraded from my 3G and couldnt be happier. I havent had a proximity sensor problem, and my reception overall is better. I can replicate the death grip issue in areas of weaker signal (office, my basement), but its not how I naturally hold a phone and Ive yet to drop a single call due due to this reception issue. Love the camera, display, faster processor etc. My only complaint: Why does AT&T charge us $30/month to tether? What is that $30 actually buying if were not even getting more data? Im currently on the unlimited data plan, but would downgrade to get the tethering if it were free. It just seems like they are charging us $30/month for nothing really. If it takes an application or special piece of software to enable tethering then let us make the one-time purchase of that software and be done with it. Or conversely if you throw on some additional data along with that $30 payment, then fine. But to charge $30 for nothing seems like a crappy way to treat your customers. Really bothers me and for the first time Im actually considering jail breaking to get around this $30 for nothing issue as I see it. So- can anyone out there actually justify what this $30/month is for?
