The iPhone 6s and 6s Plus haven't even been out for a week, and they're already old news. Behold the iPhone 7 rumor mill.

If the latest report is any indication, the next iPhone may have a huge leg up on current models: it may be waterproof. According to AppleInsider, the Japanese blog MacOtakara recently reported that so-called iPhone 7 prototypes are being produced with waterproof and dust-proof features.

"While specifics go unmentioned, Apple could be exploring methods of transplanting technology from Apple Watch," AppleInsider speculated. "For example, iPhone 7 might sport an encapsulated system-on-chip processor and water-tight gaskets. More exotic solutions include applying hydrophobic coatings to sensitive electrical components via a vapor deposition process, or integrating silicone seals at water ingress points."

In actuality, the current models might have a bit of water resistance. Some have taken to dunking their new iPhone 6s smartphones in water, and they have survived. Officially, however, these phones are not waterproof, so don't try this at home.

Other rumors suggest that Apple may ditch the all-aluminum frame found in the iPhone 5 through iPhone 6s in favor of a new material. The company may also get rid of the phone's curved glass edges, opting to give the next handset a "completely flat" LCD display, like pre-iPhone 6 models.

Of course, we won't know if any of this is true for quite a while. For now, you can always get a waterproof case like the Lifeproof Nuud if you plan to use your iPhone around water.

Meanwhile, news of a waterproof iPhone comes after Sony recently backtracked about the waterproof capabilities of its Xperia devices. Despite giving its recent waterproof Xperias — including the Z5 and Z3+ smartphones and Z4 tablet —the highest possible Ingress Protection rating of IP68 for water resistance, Sony now says you should not use them under water.
