WM5torage will export the flash memory card inside Windows Mobile 5.0 (only) Smartphones and Pocket PCs as a usual USB Mass Storage device (ordinary called "USB Disk") - effectively turning Smartphones and Pocket PCs into flash reader (albeit USB 1.0 only and therefore not too fast) and USB sticks.
It was designed and tested with the HTC Tornado Smartphone with the recent firmware update. According to the developer, it could work with other phones and even with Pocket PCs, however he isn't guaranteeing any further compatibilities.
When activated, the memory card will not be accessible from the device but from the connected PC only, as all access to the flash card will be routed through the USB connection.
However, please keep in mind that WM5torage needs a fully application unlocked Windows Mobile Smartphone.
Nevertheless, I've just tested it on my i-mate SP5 Windows Mobile Smartphone (with OMAP CPU) and my O2 Xda Atom Windows Mobile Pocket PC (ARM CPU) and it works great on both devices:
Please note that as long as WM5torage is activated, you will not be able to ActiveSync your device (via USB but for sure you can still access it via Bluetooth). Therefore, WM5torage works similar to Samsung's SGH-i300 USB Mass Storage application which lets you directly access the 3 GB HDD to fill it up with music and other media content.
WM5torage is a handy (and free) application you shouldn't miss to try, especially if you often use a USB stick to carry files around or copy them between two PCs.
