DMA has security modes, implemented by pretty much every standard baseband chip in use today (Qualcomm, Infineon, you name it). In the oldern days baseband exploits were used to crack iPhones. As far as I'm aware of, this hasn't happened in the last two generations of iPhones. So no, you do not have unfettered access to all the data, only the "baseband" segment, unless you manage to hack your security setting for the baseband. For which you first have to hack the Primary OS. I hope you get the theme..
