If you had plans to give that special someone an iPhone 4S for Christmas, you may be out of luck; retailers are out of stock, and Apple’s online store is estimating shipments within one to two weeks. So, why not take advantage of this opportunity to get a custom case made in the meanwhile? They make great personalized gifts, and even if the recipient will have or already has an iPhone 4S, they’re worth the wait.

Good news, everyone…the iPhone 4 and the iPhone 4S have the same form factor, so you won’t need to upgrade your case if you’re upgrading your phone. The wealth of iPhone 4 cases already available are ready to go for you, but some manufacturers would like to make sure you’re aware of that. And so, here’s a list of official iPhone 4S case announcements to make sure you’re ready with some protection when your new iPhone arrives next Friday.

Case-Mate have been making excellent cases for the iPhone for quite some time now, and the Monsta and Waddler are two of their latest. Both are silicone shells that offer resistance against impact whilst not restricting access to any of the ports or buttons on the iPhone 4. There’s nothing groundbreaking here, but the offer a nice design touch if you’re looking for something a little more playful.

For me, one of the most annoying aspects of being an iPhone owner is the lack of NFL licensed cases. They’ve got that deal with Sprint, you see, and as long as that’s in place, you’ll never get to fly your team’s colors on your iPhone…unless you put them there yourself. Case-Mate makes this quite easy with their iPhone 4 Hybrid Tough Mix & Match Custom Cases, and you get a stellar case out of it, too.

Colors, textures and artwork are used to set cases apart, so the smarter companies bring in some high level artists and designers to give the case some flair. What they don’t usually use, however, are photos of your kids. Or a vacation photo. Or that glistening spiderweb photo that won you a blue ribbon at the county fair. Case-Mate will help you out with their DIY Custom Case, and they’ll do it in a unique way.

Steve Jobs announced during his WWDC Keynote yesterday that Apple would be shipping their first iPhone case for the new device, to be called Bumpers. But they weren’t the only ones to promote their cases on announcement day. iLuv, Uncommon and Case-mate were also quick to show off their new accessories, so jump past the break to see what your iPhone 4 could be wearing later this month.

There are hundreds of cases available that offer several methods of keeping you and your iPhone happy throughout the day. The majority simply protect your device, but there are a growing number of options to keep your iPhone topped up with juice, and that’s what the Fuel Lite case from Case-Mate aims to do. We had a chance to play with one at this year’s Gadget Show Live event in the UK, and we were quite impressed.

Case-mate has announced the launch of Clear Armor, a protective film that adheres to a mobile phone, protecting it in its entirety while appearing invisible to the casual observer. Clear Armor is crafted from 3M’s Scotchgard Protection Film, which was originally designed to protect Apache Helicopter blades during Desert Storm. Today, 3M’s film is used more »
