The HTC Universal is a Windows Mobile 5.0 Pocket PC PDA manufactured by High Tech Computer Corporation.

It was sold by many different vendors under the names of O2 xda Exec, Orange SPV M5000, Dopod 900, Qtek 9000, T-Mobile MDA Pro, I-mate JasJar, Vodafone v1640, Vodafone VPA IV, E-Plus PDA IV, etc.

Most network-supplied versions of the Universal are shipped SIM-locked, with the O2 XDA Exec being a notable exception.
