I have a question for all you android experts here, if I get a SIM-Free "Unlocked" Samsung Galaxy S would I still have to root it to install cracked files? Or could I just download Astro of the Android Market place and install cracked apps right of the bat?

You dont have to be rooted to install cracked apps. So yea you would just need a file browser

Thanks man, you have justed made my day! Another question what does rooting actually do on an android phone? Sorry, if I sound like a noob, I'm quite new to the android OS......

rooting a phone enables super user account(admin account) on the phone mate, there a few apps out there that need this level of permission (e.g galaxy s lagfix)

Cool, so basically when you get an android phone of the shelf it's locked into basic user mode and inorder for you to run apps, which require the admin mode you have to root it. Thanks for the explaination.
