I read the user guide, backed up my phone list numbers from my old phone, but found that directions to transfer the phone numbers did not work on my iphone 4. Grrrrr! What I read in the instructions does not match what I see on the screen. Also, Apple's use of the word "contacts" is used to apply to both email addresses (which did transfer easily) and phone number contacts (which did not). This can be confusing.
Has anyone transferred a phone list from their previous "dumb" phone (backup assistant enabled) to an iphone4 (not backup assistant friendly).
