Well, it does seems like an age, but finally LinkedIn is now available on your Blackberry, iPhone or internet connected phone. So you can now get all your contact access while mobile. All you need to do is go to https://m.linkedin.com on your device and log in.
So if you are an avid LinkedIn user then this could really be a powerful tool for you. When you meet great people, you can connect to them on LinkedIn straight away at the meeting - now that is a great conversation piece!!
