So I been away from the iphone for a few months. I had the iphone 4 but left right before the jb came out for it. So what is the current state of jb for the iphone, if I was to buy one again or even wait for the iphone 5? Tethered or untethered? Wth is a blob? lol. There isnt really a faq to read or is there? But any help would be greatly appreciated.
