I just bought my first iPhone and so far I'm pretty annoyed.
For example, the Answer and Decline button for incoming calls are backwards, Answer to the right and Decline to the left.
Since I've used the left button to answer a phone for as long as I can remember (and still do on my home phone), I' actually sometimes press the Decline button by mistake. Really annoying. I don't want two standards, one is enough for me.

So, if someone knows a way how to change this, please let me know. I've tried searching for this without any luck.
My device is a iPhone 4S, IOS 5.0.1, Jailbroken.
