I've had the Eris since January and have been using the stock exchange app. I'm pretty happy with it except that it just doesn't seem to push the emails through or not at all if I'm not using it even though I have it set to push upon arrival and it is excluded from my task killer. Having said that I'm giving touchdown a shot. The interface is pretty cool, and I like how fast I get my emails now. However, before I copy my contacts over to my phone, I want to avoid the mistake so many others have made and do not want to get duplicate contacts, so... I'm reaching out to the masses to find out the best way to do this. I have not yet disabled the stock exchange account so both are running, but only contacts on stock app are syncing (as I haven't activated touchdown to sync changes yet as it told me to copy my contacts to my phone before I activate it) Any words of wisdom to avoid duplicates? Thanks!
