Rumour has it that Apple is set to announce new iPod nano designs at tomorrow's media briefing. Certainly, the invitation we were sent requesting our presence suggested a music-related launch.

Despite some ropey snaps doing the online rounds, there's not yet official word on a fourth version of the iPod nano, though. That hasn't stopped some companies jumping on the nano bandwagon, however.

Anticipating interest in the new nano design, UK online retailer easyishop has rush-released some protective cases for the yet-to-be confirmed MP3 player. The Hardcase protects your theoretical iPod nano 4G from bumps and scratches and costs £19.99.
