So the "new iPhone" is probably already pretty cemented on terms of design. We have been hearing rumors for a while suggesting aluminum backing, Recently a report believed it to have glass back. So my question to you is which would you prefer? Or do you want something else entirely? There are a lot of factors to consider such as weight, durability, feel, flexibility, thermal conductivity, scratchability, texture, signal penetrability, etc.... So it's really not a simple decision.
