I recently unlocked a 3G iPhone on the T-Mobile USA network. Whenever I recieve an SMS from another T-mobile number, the US calling code shows up in the number - i.e. +1 (555) 555-5555 as appose to the usual (555) 555-5555. This is definately annoying seeing as the message shows up as the number with the US calling code and not my contact's name. Is there a way to fix this or should I just start saving all my T-mobile contacts with the US calling code in the number? Thanks.
