Pocketnow has posted a review of the i-mate K-JAM (a rebranded HTC Wizard). The review looks at the device itself (essentially a slightly thicker i-mate JAM with slide-out keyboard), the software it comes with (including Voice Dial using a Bluetooth headset), and benchmark results. The review also features plenty of pictures.
One issue raised in the review is that some of the third-party software included with the K-JAM does not support Windows Mobile 5.0. For example, neither the anti-virus and Skype software worked.
Overall, Pocketnow is pretty impressed with the K-JAM but they are looking forward to future ROM updates to fix some issues and add new features.
