Best SQ for uploaded CD's

[Hudson01]

Well, i have just got the phone and managed to sign up to itunes.... put the sim in.... and even get it going in terms of adding a couple of free apps.... but now i have downloaded onto my computer (and the itunes libary) my first CD. I want to put it onto my iphone in the most uncompressed format i can, ie for the very best i can get in sound quality. What is my next step ? Is there something i need to alter on my phone to get this to happen or is it something in itunes i need to access ? I have the 32gb version so hard drive space is not an issue. Thanks.
