In a Patent Flash Report that we posted last week partially titled "Will the iPhone ever be Waterproof?" – we covered Apple's system for creating a water seal involving the use of both a sealing tape such as DuPont's Kapton and a soldering paste. In today's newly published patent application, Apple reveals that they're working on waterproofing a key device component using silicone rubber as a sealant. The patent also reveals that their solutions could eventually extend on through to the iPad and even the MacBook. Apple isn't there yet, but their definitely working on ways of better protecting us against devastating water damage so that we could keep on working, surfing and enjoying our devices without unnecessary disruption.
