I subscribe to iphone 3GS plan this July, so I ask Digi center they said u can buy an iphone 4 without contract starting from 1st of November, if I purchase now I'll be tie with 24 months contract; thats mean I will tie with 2 contract.
What I dont understand bout the 2 contracts is I'll only continue paying my existing bill, or I need to get another digi number???
