Ideal settings for fonts on iPad?

[Fordeka]

I have a font which is about the same size on its atlas as the largest instance of it on a UILabel. On an iPad 1 the font atlas texture type is set to "texture" the 1:1 instances of the font show pixelation around the edges and the instances half that size look fine. When the atlas is set to "GUI" the 1:1 instances look fine but the half sized ones have artifacts around the edges (look like they have been put through a sharpen filter too much in photoshop). It looks fine on the PC with either setting. Is there any setting I can change the make the font look right in both instances?

Check the filtering on the atlas texture and play with it, setting it to different values. Also double check the atlas texture to make sure it's not being compressed as PVRTC compression used on mobiles is truly horrible for UI textures.
