I need to copy my phone contacts in my PC. Is PC Connectivity Solution the right software?
Yes, it can be the right software if you have a Nokia device. PC Connectivity Solution is developed by Nokia and allows you to to synchronize your phone with your computer. If you have other mobile model you will need an adequate PC suite. For example for BlackBerry mobiles you can use BlackBerry Desktop Manager, for Sony Ericsson devices - Sony Ericsson PC Companion, for LG phones - LG PC Suite. I suggest you to visit your mobile developer website and to check for a similar utility.
