Three lovely models hit the mobile catwalk...Nokia has unveiled a range of 3G phones which it hopes will boost flagging handset sales. The 7650, the most expensive of the three new models, features a colour screen and an in-built camera, and will begin shipping in Europe and Asia in the second quarter of 2002. The phone, which operates on GPRS technology, and features multimedia messaging services (MMS), will support Sun's Java software. The company said it expected all new Nokia handsets to feature MMS by 2003. Two cheaper models, the 5210 and the 6510, will ship in the first quarter of next year.
