Is is when u on the phone? If thats the case u cant change anything its the case for all phones. I.E. today spoke to my operator to change my billing address and to send me charges if using my phone abroad and i heard the beeps in the headset. Everytime i get a txt while on the phone same thing. N i think its for all fones. Really theres nothing u can do. Jus to mention my iPhone is not jailbroken. Maybe others have solutions?
