The "New Contact" and the "Edit contact" screens in the iOS 4 Contacts app have been heavily changed. To worse!
Gone are the elegance, the simplicity and the easy understanding of what to do to add a new phone number, or a new address, etc.
Why bother to change what was quite perfect?
Also, still no "Duplicate contact" function (as there is in the Mac OS app), that I have repeatedly requested to Apple feedback, which would be very useful when you have to add several contacts of the same company or organization (name of company, fixed phone lines, postal address and domain of the email address are the same, so duplicating the first added contact you can easily add several further persons simply changing name, surname, mobile phone number and the first part of email address)
Mines doesn't look different at all.
