I just got an iPhone four and put it on the straight talk plan by buying a SIM card. Why can't I use data? I can only use it with wifi?
I've also had some problems.
With the touch screen not working, how do i recalibrate the screen? and dropping my calls. My microphone may be broken but people can't hear me When I talk.i bought the phone refurbished so I don't know how much of it is the phone or me trying to use straight talk with it. It's factory unlocked and not jailbroken.
