Thank you for your answer. However, when I got my phone, at the Verizon store they used my Gmail account to transfer my contacts from my BlackBerry. I tried using Groups, but none of my contacts appear in the list to be added; they're all associated with the Google-synced Gmail. On my BlackBerry & previous Palm, it usually took 3-6 letters of a company name or city to be able to select the correct contact.
Groups might be a good filter, but I (and I'm sure others) would need for the contact search function to bring up matches from any field of contact information (name, company, address, city etc) to be usable.
