One of Gear Diary’s favorite accessory manufacturers, Speck Products, has announced the immediate availability of four new additions to their Artsorojekt line of Fitted cases for the iPhone 3G and 3Gs.

I previously showcased some of the Fitted designs here.

The four limited edition cases, which are designed by select members of Artsprojekt’s international syndicate of artists are now available in all of Apple’s retail stores.

From brightly colored “Waves” and cute “Campsite” by Montreal-based Eve Duhamel to pleasingly patterned “Bosque” by Buenos Aires duo Yo Amo La Leche and enchanting “Chemical Girl” by Caia Coopman of Oceanside, California, these designs match a fresh, young visual perspective to some of the world’s hippest portable technology. All are all carefully printed on soft but durable fabric, which is then fused to Speck’s road-tested Fitted two-piece snap-together hard shell design. The upholstery-style exterior increases in-hand ease while helping to secure iPhones when set down on surfaces.

These awesome new Fitted Artsprojekt edition designs, as well as previously released editions for the iPhone 3G and 3GS, are available now exclusively at Apple Stores for a M.S.R.P. of $39.95.

You can see the designs up close and personal by visiting the Artsprojekt section of the Speck web site here.
