TechFaith , a Chinese Wireless Communication company, has announced the launch of the world's first WCDMA/GSM dual mode pocket pc phone, named "Twins". Up until now, costumers who wanted to use two SIM cards on their pocket pc phone had to turn off their phone every time they wanted to switch from one SIM card to the other. The new dual-mode Twins phone allows the user to use both SIM cards at the same time. In this way, the phone can work on two cellular networks and even if the networks are based on different technologies, such as GSM and WCDMA.
