Why don't you create an update were iPad 2's can have Bluetooth 4.0

A: You are not talking to Apple. We can't "create" anything. We are users just like you.

B: It is physically impossible for a software update to magically make the hardware in the iPad 2 support Bluetooth 4.0. It's a hardware issue, not a software issue.

Because it's a hardware change as well as software.

Nobody here creates Apple updates as this is an Apple hosted forum for follow users of Apple products. You should submit feedback to Apple through their official feedback link - http://www.apple.com/feedback/
