I got my unit connected to PC. I found a thread that had some files to download.. but where do I put them? I didn't purchase a memory card.. do I need to in order to get marketplace working? I've never installed anything before. This is my first experience with Android. I bought it as a gift for someone, but figured I should at least put Marketplace on it before giving it to them. Also, can I over clock without rooting or no? I tried to get it to connect to my wireless internet at home, but it doesn't work. Keeps disconnecting.
