There's some talk about a possible recall by Apple for the iPhone 4, according to the front page news and other sites/blogs. Although it's pure speculation that Apple will actually do so (let's face it, Jobs will likely stay defiant 'til the end), I can still picture it happening, especially if the new JB comes out before then. It would be their chance to recall millions of iPhone 4's, reflash those units with a possible 4.0.2 or whatever it is after the "signal bar display fix", thereby plugging the exploit.
I know people who are desperate for the JB would be pissed to no end, especially those that knew better than to try to update to 4.0 but "accidentally" did anyway (I'm looking at you Arisian
), but I think it would be in everyone's best interest to release the JB after the ENTIRE antenna issue is resolved, with Apple clearly detailing what they are or aren't going to do about it in some definitive way. It would be a shame if the JB was released, only to see Apple recalling the iPhone 4 the very next day and reflashing with new firmware to fix the exploit. JB or not, people would return their iPhones if that meant no more antenna/signal issues (at the expense of their JB). If I had an iPhone 4 I knew I would.
