Hi there, I'm very, very new to the forum, and I'm not even sure if this is posted on the right place, so if it isn't, could a mod maybe move it for me?(sorry for the inconvenience :/) I've had Xcode 3.2.6 for a while, and created simple programs for it and thats all going fine, but I see that there is a 'newer' version(Xcode 4) - I say new, because I've only just realised there is one. My questions are; -What are the main differences between the two? -Where and how much is it, if it does cost anything, do i buy it? I've been doing research on teh interwebz but I figured I'd come on a forum and ask the pros. Thanks for any help guys! Andy.
