Looking to use your iPhone in a harsh environment without damaging sensitive internal parts? Now with the Concord Keystone ECO MarineCase you can safely bring your iPhone underwater without sacrificing full functionality. The case is designed to protect an iPhone 4 or 4S in up to 20 feet of water.

Whether it's dust, sand, snow or rain threatening your iPhone, the MarineCase keeps the device safely protected inside with secure locking design. With a rating of IP58 you never have to worry about using the iPhone while on the beach, fishing, swimming, kayaking or any other activities close to the water.

App Store developer Adam Bell has released a new jailbreak tweak that allows you to customize the way you unlock your iPhone. Stride replaces your password screen with a customizable gesture system allowing you to do away with lengthy passwords. Or it can double as an extra security measure by allowing you to use a gesture and password to access your iPhone.

"Even though Stride is pretty secure on it's own, for best effect you should set a PIN/Passcode to make things extra secure," Bell explained on Cydia. The PIN unlock will appear after you draw your customized gesture, or you can bypass the PIN code in the Stride preference panel. Stride is available in the Big Boss repo for $2.99. It's compatible with the iPhone and iPod touch, but not the iPad. Stride requires iOS 5 or higher and a jailbroken device to work.

So you've decided to close your Instagram account and save your retro photos from the clutches of Facebook. Many users have enjoyed the creative filters on Instagram, which are known for giving the images an analog, film-like look.

The good news is there are many photography apps in the App Store with even better filters. Many of these photo apps are free and provide several options for sharing and showing off your pictures to friends. Here are 8 of the top alternatives to Instagram available on the iPhone.

Now that Instagram has been acquired by Facebook for a cool $1 billion, users are concerned about changes to the service. Even worse, some iPhone owners are concerned that Instagram will soon be inundated by advertisements or modify its privacy policies.

Even though the official statement by CEO Mark Zuckerberg explains that Facebook is "committed to building and growing Instagram independently," this hasn't alleviated everyone's privacy concerns. Luckily for them, there's still time to download all Instagram photos and quit the app forever.

Are you ready for another six months of iPhone 5 rumors? You better be, because the Apple rumor mill is fired up and going full force today! According to 9to5Mac, "Apple has internally seeded a prototype next-generation iPhone with the iPhone 4 design." The new prototype labeled "N96" is being used to test a variation of the A5X chip that powers the new iPad in an iPhone.

Topeka Capital Markets analyst Brian White (via AppleInsider) came back from a recent trip to Asia with more "new design" rumors. White told investors that the next-generation iPhone "will be the most significant iPhone upgrade with a four-inch screen and a new, sleek look" that he believes will require a "unibody case." 9toMac also noted in their report that the "actual next-generation iPhone is specifically said to not include the iPhone 4/4S design." However, Apple is using older casings to test the N96 prototype to avoid leaks of the new device. The new iPhone prototype is also supposed to feature 1GB of RAM.
