Why is nobody mentioning that Xcode 4 is not a free download? It's only free if you already paid $99 for the developer account. It's $5 for the rest of us.
Though $5 is not a huge amount, it's difficult for me to send that money to Apple. All I have is a debit card. Getting a credit card is impossible for Indian students. I'll have to call an "adult" (I hate that word) and convince them to let me use their credit card for an Xcode purchase.
On the other hand, The Pirate Bay has a free copy I can grab ...
