Well, this is less of a problem and more of a nuisance than anything else, but I'll say it anyways.

On GitP, you can double click the "color letters" button to color your letters whatever color you want them to be. On the iPhone, it will only work the first time because you manually open up the entire list of colors and choose from those colors what you want your text to be dyed. If you try to double click the button on the iPhone as you would on a computer, it will give you the color in the rgb number form and not something like "[COLOR ="Blue"][/COLOR]" for instance.
