Today we take a look at some of the biggest and most game-changing rumors circulating about the new iOS 7 update and release of either the iPhone 5S or 6. From release dates to spying technology, there's a little bit of everything.

With the release of iOS 7, there will definitely be a new edition of the ever-popular iPhone. The only question is, will it be the 5S or the 6? The difference, of course, is a big one. With the 5S we should expect an iPhone similar to the fifth generation, whereas with the 6 we can expect some serious upgrades. As for when the phone will be released, that's still all rumors.

"During the spring, it was reported that Apple will hold a media event on Sept. 10 to unveil the finalized iOS 7 and a new iPhone to go along with it...If history means anything, the next iPhone device will be released on a Friday, which could mean Apple has Sept. 13 in mind. This would be the first Friday to follow the supposed media event. None of this has been confirmed by Apple however," report the folks at autoworldnews.com.

They aren't the only one predicting a September release either. According to the TELUS "Upcoming software updates schedule," the iOS 7 upgrade is pegged to be released sometime in September, which is in line with announcements that it would be released sometime in the fall.

So what can we expect once it does drop? Everything is admittedly just a rumor at this point, but one of the more likely scenarios is an upgrade to the way password protection is used. So far there have been lines of code in iOS 7's beta 5 that point to a thumbprint scanner on the home button, and there has also been talk of face recognition software.

There's also been water cooler chatter about Apple attempting a slimmer design for the iPhone, though that would probably only happen if they decide to debut the iPhone 6. It is believed that Apple wants to keep up with the flat designs many people have loved about some of the recent Android phones.

With the iOS 7 we've also seen a highly-updated color scheme, one that has gotten mixed reviews. Then of course there is also the "Frequent Locations" feature, which displays and tracks a user's latest locations. Though many have criticized this feature in the wake of the NSA scandal, others steadfastly maintain that there is nothing to worry about.

"It's a feature that has to be enabled by users on setup (allowing the iPhone to use your location has been opt-in for years), and will now also include a user-facing interface so you can actually see what's been recorded. And that, apparently, might scare people. Not the headlines that make it sound scary, of course, but the non-hidden, still relatively benign, still opt-in and disable-able, user facing feature," observes Rene Ritchie of iMore.
