I have tried synching my data from ACT (contacts, tasks, calendar) on my Win XP pc and Outlook (notes) to my iphone 4. I have been using companion link. It is supposed to be able to do this, but there are a number of on-going problems. Companion Link has at different times: - duplicated all contacts on the iphone - erased all contacts on the iphone - created multiple copies of each note on the iphone when it was not set up to do this. I have contacted companion link tech support many times over the past 2 months and they are unable to get it to work right. Can anyone recommend a better product? At the moment, I have two copies of all contacts in the iphone native contacts. Does anyone know how to delete all contacts so I can start fresh? Thanks.
