AT&T makes Lumia 900 Gel Cases available for purchase
One down side of the AT&T Lumia 900 is it doesn't come with a Gel Case unlike the Lumia 800. On the other hand, this will allow you to buy a color you may prefer and Nokia gets to shave a few dollars off of the 900's price to hit that $99 price point.
We know that AT&T will have many accessories available in stores for the 900's release including 3rd party cases, screen protectors, Monster-Nokia Purity HD headsets and more. To kick that off, AT&T has already listed those super sweet Nokia Gel Cases on their site and you can buy them now.
Fetching for $20, they are certainly a bit pricey...heck, those are Apple prices. But, we have seen these cases in person and have a similar one for our Lumia 800 and they are fantastic. For one, you can change your device's color just by slipping one on (in this regard, the glossy-white 900 is your best bet). The other great thing is not only does it offer a global "bumper" for the device to protect against scratches, nicks and bumps, it's super thin and adds virtually no bulk to the phone.
They're exquisitely crafted to fit the Lumia 900 like a tight glove and come in three colors: black, magenta and cyan. Not a bad choice and we think you'll love 'em.
