We are starting to replace our current BlackBerries with iPhones. We are having difficulty finding the right combination/application to work with synchronizing our company contacts and personal contacts. We are using Lotus Notes. Our current company contacts DB is over 5000 contacts. We don't want to store our company contacts on a public server like Google. Our corporate office is in charge of the Enterprise servers on this. They will not allow us to sync our company address book wirelessly, only the corporate one. How can we do this cleanly and easily? Is there an app that would accomplish this task that would keep our company contacts secure? Or is there one that we can use that integrates locally with Lotus Notes?
