pod2g has been making quite a bit progress in jailbreaking iOS 5.1. Last week, he reported that he had all the exploits for iOS 5.1 jailbreak and even managed to bypass ASLR.
However, it looks like there is still quite a bit of work to be done as has just tweeted:
ETA for 5.1 JB: no clue! We’re going to set pieces of the puzzle together this week. We could have issues… Could be 1 month maybe 2…
Maybe never… (!)
I know 1 month seems long, but it’s short to work on a project like this when it’s a hobby and you’ve other things to do as well.
So please be patient and don’t complain or ask him about the jailbreak progress on Twitter, we’ll let you know as soon as there are any further updates.
