So a while ago when i first got my unibody macbook and had an iphone 3g i had read that there was a problem and something to do with the USB left you unable to use DEV team unlocks on them, has this changed. I ask because i have just gotten a 3GS and was deciding to jailbreak or not. Is jailbreaking worth it to you guys? What are some of the cool things you can do is there still Installer? Let me know please thanks!!
