I've had some trouble finding skins that work with WQVGA, so i'm just sticking with the standard skin. QVGA skins may work, but I haven't tried. Take a look at this thread:

Manual is here:

To choose on the 2 key layout, you can do it two different ways:
1. Touch the key you want, and slide LEFT to get the left character, RIGHT to get the right character. So on "g h" for example, touch the key, slide your finger right for "h", slide left for "g".
2. You can also touch the left or right side of the button and it will auto return the key closest to your tap if you don't slide (this only works when T9 is off though!)
Have fun.
