1. In android there was a neat option in contacts which hid all the contacts which didn't have email IDs, they were mostly from my google's contact list and from facebook. However they are back in iPhone and filling up a lot of space, so how do I set it to display only those contacts which have phone numbers? 2. I imported all contacts from android using Microsoft Exchange. How do I make these contacts display the thumbnail in my contacts list? 3. Is there any way to set speed dial? When I tried dialing just "2", it gave "Unknown Application" error. 4. Is there any way to just "swype" the contact name to call someone rather than go inside and click on the phone number? Thanks.
