The "perfect" resolution

So I’m trying to create a background, but I’m not quite sure what dimensions I should be using? When I use 480x320, it looks perfect on a regular iPhone, but it has black bars at the top and bottom if I run it using an iPad, and black bars appear on the sides when using an Android device.

Is there a magic dimension I can use for my backgrounds? Or should I just shove in the largest image I could make, and just let it overflow (my game isnt that texture heavy, so it shouldnt overload the memory)?

I tend to use 570x360 for a situation like this. That should give you a big enough boundary for most, if not all phones and tablets. Give it a go and let me know how it goes!
