Handheld PC maker Handspring has this week begun selling its Treo 180 communicator, a combined mobile phone and PDA (personal digital assistant).

Handspring is making its Treo 180 and 180g devices available in the UK, Germany, France, Sweden and Norway through stores and localised versions of the Handspring website, the company said in a statement.

The PDA is designed to work over GSM/GPRS (Global System for Mobile Communications/General Packet Radio Service) mobile networks and uses Palm's operating system, Handspring said.

Here in the UK mobile-phone operator O2 retails the Treo for £299 when it's bought with a connection to its BT Cellnet service, Handspring said. Without the BT Cellnet connection plan the Treo will cost a whopping £499 (for customers living outside of the UK), the company said.
