I read the FAQ that's stickied, but seeing as it's dated at '08, I figured I'd just double check with you guys. I know some questions are just speculation and there's no valid answer, but attempts are welcome. I was recently told that modding a 360 is useless if I wanted to play online. I was also told that a recent update rendered the modded HDD's useless and made it so that the Xbox 360 not read anything except genuine Microsoft HDD's. If this information is wrong, then on to the questions: A JTAG is just for homebrew meaning it should never be used with online multiplayer games due to banning? Do you need a JTAG to play backups, can you play backups online? If so, does anyone have any RECENT experience with being able to play them online without being banned/amount of time they've been playing backups online? Is there any real point to modding a HDD if you're not going to mod your 360? Is the max size of a modded HDD 120GB or is it whatever you want it to be? Sorry about the noob questions, new to this stuff.
