An iOS update to fix the zombie passcode security bug and Exchange issues is expected to arrive around February 20, according to new claims from German-language Apple site iFun. The site, which previously played Nostradamus for the impending release of iOS 6.1.1 for iPhone 4S, says iOS 6.1.2 is already in the works and will be seeded to users within the next week.

Those of us not using an iPhone 4S are most likely still using iOS 6.1. And as it turns out, iOS 6.1 isn't quite as polished as it should be—Microsoft issued a warning earlier this week to Exchange sysadmins, instructing them to throttle or block iOS 6.1 users due to a bug that led to over-polling on calendars and mailboxes. Apple acknowledged the bug in a support document soon thereafter, saying it had identified a fix that would come in a future software update.

But then an old and familiar iOS bug reared its ugly head again. A flaw that surfaced in iOS 2.1, then in iOS 4.1, and now in iOS 6.1 can give unauthorized access to your iPhone's voicemails, contacts, and photos, even if the device is PIN-protected. Again, Apple acknowledged the issue and told AllThingsD that a fix was on the way. "Apple takes user security very seriously," Apple spokesperson Trudy Muller said.

Both of those issues will get attention in the upcoming iOS 6.1.2 update, claims iFun. If you haven't upgraded to iOS 6.1 yet, it may be worth waiting until next week to see whether the update will be any better—in addition to the above two bugs, iOS 6.1 also caused 3G connection issues for iPhone 4S users. At this point, it seems safe to say that the 6.1 software didn't quite live up to many Apple users' standards, so here's to hoping for iOS 6.1.2.
