No iphone currently sold is connected to its modem via DMA. They've all got some type of iommu.
Given that most traffic is encrypted (eg any major website via https, or mail provider with smtp-over-tls, or most apps via https), a baseband vulnerability isn't a great deal of help without an iommu bypass (AFAIK only one has ever been publicly disclosed for ios, and it took the researchers over 6 months).
IIRC correctly (from a few years back) the pixel phones also have one, but most Samsung phones did not.
