Question 1: How could pod2g have an untethered 4S and dev teams still haven’t released tools to achieve this at home?
Answer: The exploit I used to inject the untethering files to the 4S relies on having a developer account, and can’t be released publicly. It’s the same reason why @MuscleNerd has an iPad 2 tethered jailbreak but couldn’t distribute it. So, we need to find a distributable exploit to remount the system partition read/write and to set Corona files at the correct places.
Question 2:Why A4 version of Corona was easier to release?
Answer: Because a tethered jailbreak is a good way to install Corona!
Question 3: Why don’t you do a tethered jailbreak then?
Answer: A tethered jailbreak also relies on an exploitable vulnerability that we still haven’t found yet !
He also replied indirectly by answering himself like below:
” pod2g, release this stuff quick, I’ve waited enough now.” ” If I could, I would !”
