I imported all the contacts from my phone on to my f90 but whenever I receive a call the name doesn't show up, just the number. Whenever I make a call, however, the name does show up. Does anybody know how to fix this? Thanks in advance.

Do the phone numbers in the phone have '1' before the area codes?

no, the numbers do not have a 1 before the area code. Does it need to have a 1?

Here's a recent post I started that addresses this known issue:
