my 8320 just arrived in the mail, was trying to make my first call but a prompt keeps asking me for the area code.. i tried to go to options but for some reason, i could not find the "smart dialing" option where i should be able to set the area code prefix and number length.. i have v4.2.2.171

Press the green phone button. Then press the menu key (left of trackball) and select Options. Then select Smart Dialing.

Super Mod JC, thank you big time.. my unlocked t-mo curve is now 110% operational here in the PH.. and i must admit i am going crazy!
