Social network sites don’t have to be just for your personal life. Networking in the business world is crucial. If you aren’t already a member, you should consider joining LinkedIn, a social networking site for your business relationships.
Though LinkedIn doesn’t offer an official Android app, there is one called ConnectIn by Stevel. It lets you synchronize and integrate your LinkedIn contacts information to your Android. It includes phone numbers, headlines, photos, and status updates. You can also view profiles and send messages with LinkedIn’s InMail.
If ConnectIn doesn’t suit your needs, you might want to check out DroidIn. It offers features similar to ConnectIn.
