Jail broken AT&T iphone 4 for T-Mobile. Why can't people hear me?
I bought the jail broken iphone 4 back in May and before it used to make phone calls just fine. After a couple months people can't hear me, but I can hear them. I can make phone calls and people can call me, but I don't know what the problem is. There's no water damage or anything. What should I do?
Btw, I have good service all the time, so it doesn't make any sense.
