The home button on my ip4 is getting even worse. I think I'm going to bite the bullet and finally have it replaced in hopes that a new phone won't have the same problem. I'm currently running 4.2.1 jailbroken and unlocked with baseband 1.59 which I believe is the latest unlockable baseband, correct? Wonder if the Apple store would even have any older units in stock that have an older baseband... If not, hopefully by the time I decide to sell this model, an unlock solution will be available for other basebands.
