Seidio is now accepting pre-orders for their new Desktop Charging Cradles for the 8900. 8350i, & Storm. These cradles are special since they allow you to use them without having to remove your devices skin or case. It looks like it only supports Seidio cases or skins but still its pretty cool. They do not look as slick as the RIM charging cradles but they do work. Just as a reminder the 8900/8350i cradle does not let you sync while it charges but the Storm cradle seem to let you sync and charge.
The cradles are going for $24.95 during the preorder and may jump up to the regular $34.95 afterwards. Looks like shipping begins sometime around the end of the month.
They also have a 10% off coupon going on now with no order minimum. Just use the coupon code FF0331 to get the discount during checkout.
