A few years late in response... but the only way to do it cross network is at the store with the contact swap machine.

I have had a I930 and love it howver I am contemplating switching my phone carrier to Sprint. I have been using a 7130E for a few months as my blackberry and really like it, however I deard changing over my contacts manually. I have fooled around with the Microsoft Active Sync without too much success, so does anyone have any ideas how to accomplish this task?

Thanks in advance for any response.
