Your shiny new iPhone 4 may arrive as early as tomorrow, but if you want to keep it shinny and new for more than a few days, you’ll need a case of some sort.  Trouble is, at the moment cases for the iPhone 4 are scarce. So if you want a case for the newest iPhone before it becomes a portable scratch collection, here is a brief rundown of your current options:

MiVizu iPhone 4G Skin Case: one of the few iPhone 4 skin cases available on Amazon.com.  The case is $16.95, available in a range of colors from black to pink to clear and  is constructed from “thick” silicone. 

Includes a screen cleaner and a 90 day warranty.

Apple iPhone 4 Bumper Case: Apple’s new case for the iPhone 4 is called the Bumper.  The case is constructed of rubber and plastic and, being from Apple, will surely fit the new iPhone perfectly.  Bumpers are available in black, blue, white, green, pink and orange. 

This little gem’ll set you back $30 at the Apple Store (plus tax).

Favorite manufacturers like Marware, Case-mate, and Belkin are hard at work on iPhone 4 cases, but not one iP4 item from these companies is currently shipping (or is marked as backordered). 

If the cases above don’t tickle your fancy, try eBay.  It’s HQ for hard-to-find accessories for new gadgets, and iPhone 4 cases and skins are no exception.  You’ll find hundreds of auctions there, many available with instant BuyItNow buttons, for cases designed for the new iPhone.  We recommend searching for “iPhone 4G cases” rather than “iPhone 4 cases” because the number 4 appears for “for” in many auctions for other iPhone models’ accessories.
