When I got my Treo Verizon unloaded my phone list from my old Motorala cell. I want to load my Act! data base into the Treo but dont want to loose my contacts. My phone says I'll loose everything in my phone contacts when I download my Act so how do I save my cell #s when I download my 4800 contacts in Act? and will the Treo handle a database that big?

Help before this device gets thrown out of my car window! :
