Make it small, very small. That was the mission statement for this project. iMono has a clean looking SIM and multi-card reader which is housed in a USB chassis for quick connection to your PC.

Supports all the popular mobile card formats; mini SD Card, Micro SD (T-Flash), Secure Digital Card, MMC Card 4.0, MultiMedia Card, MultiMedia Card Plus, RS-MMC (MMC Mobile), RS-MMC4.0 (MMC Mobile 4.0), MMC micro, MS / MS Duo / MS PRO Duo, Mobile SIM Card. Also comes with a SIM phone book software suite which is extremely nice - who wants to input contacts via a phone pad - not me.
