I sucessfully jailbroke it but when i click on cydia, it does not launch. Any ideas???
ya… same here, and suddenly safari crashes too, is this just a bs jailbreak? cuz that’s the feeling I’m getting
Poor JB, just a race to be first, not quality… No functional cydia… Almost looks like it just throws up a fake cydia icon and calls it a day… But if you restart it is clearly tethered, else nothing happens… I went back to 4.2.1 and no crashes, unlike my days with jail broke 3.2…. 4.2.1 is pretty decent other than no wifi loggin utilities and that stupid crap they did with the orientation lock…. Might not JB this time… JB always makes the system less stable and more likely to crash but this attempt does nothing except corrupt the sys… AVOID!
jailbreak for 4.2.1 is still not stable, u need to wait for 4.2.1 update
