The iLID began life as a Kickstarter Project. (Here’s the page.) I got in on it later, so I ordered one retail (I ended up with two, so be on the lookout for a giveaway). Here’s what the website has to say about it.
The World’s Thinnest iPhone Wallet! The iLID iPhone 4 Wallet Case is the thinnest Wallet iPhone (Patent Pending) in the world. Its ultra-thin 17mm profile means you’ll never be weighed down by an iPhone Wallet again.
What I Like: Light; Not as thick as I expected; Let’s you go out with just your phone; The back door doubles as a stand
What Needs Improvement: At $39.95 it is a bit pricey for what it is; The sticker on the back was a pain to remove and left some residue
Keep your eyes out for a chance to win one!
