Thanksgiving with Apple
With Turkey Day a few days off, today Apple publicly released FW version 4.2.1. As always, ultrasn0w unlockers please stay far far away from this official firmware (and all official firmware). Wait for the ability to create custom 4.2.1. IPSWs that dont update your baseband! If youre not an unlocker, read on!
The best news of all is for owners of iPhone3G, older iPhone3GS, and non-MC iPod touch 2G. Due to a combination of our original pwnage2 exploit, the arm7_go exploit, 24kpwn, and limera1n, your device is just as jailbreakable as ever. You reap the full benefit of an untethered 4.2.1 jailbreak.
Next are the owners of all the more recent devices. The good news there is that due to geohots limera1n exploit, all recent devices can be jailbroken (this will be true until Apple released new hardware that fixes geohots limerain exploit in the bootrom). The bad news is that right now, the 4.2.1 jailbreak is *tethered* on all of these recent devices. A tethered jailbreak means that each time your device loses battery power or needs to be rebooted, you must attach it to a PC or Mac to boot into the jailbroken state. @comex is working hard on a method that may untether the 4.2.1 jailbreak, but it will require you to have your 4.1 SHSH blobs in order to use it. No word on how much more effort it will take though (please dont bug @comex about it!). (We also have an alternative method that may work, but @comexs method is much more elegant.)
So when does all this 4.2.1 jailbreak action happen? Well if youre a JB developer or tinkerer, youve already probably used the redsn0w mentioned in our last post to jailbreak 4.2.1 and at least get SSH working. But beyond that, there are still some last minute issues with MobileSubstrate and comexs kernel patches that are being fixed. Well tweet and post a blog update when its all available (we hate to give ETAs, but barring any unforeseen problems, probably later today).
In the meantime, please make sure you have your 4.1 SHSH blobs for all your devices. These will be important even for firmware beyond 4.1 (using both comexs method and our alternative, depending on how each of them turn out.)
ultrasn0w unlock: After redsn0w is officially released with the new Cydia and kernel patches, well be able to assess the unlock situation. Its already looking very promising though, so expect the unlock for the 3G and 3GS to be coming this week. The i4 unlock is taking more effort though, and no further concrete info is available about that yet.
Feel free to ask questions in our comments section below, where weve got some awesome new additional moderators sherif_hashim, dhlizard, and Frank55!
No one said jailbreak or unlock would be released on the same day as 4.2, a few days after they said. But giauto den agorazo locked iPhones ever Greece has them factory unlocked ! Did you get it from America eipes?
no one said as soon as 4.2 was out. it was said a few days after. not as soon as. but no there is no unlock. we can only relay information given by devs that has now turned into the iphone 4 wil take longer. no idea when..
but this is why i never buy locked iphones. now you have to sit there relying on unlock tools to even upgrade firmware. sucks for you
