False, Apple does NOT make a 4 GB iPhone !
2^32 = 4,294,967,296 = ~4.3 GB !
From the early Geekbench 4 reports, ALL members of the iPhone 11 family "appear" to be in the 3.7-3.8 GB range !
That ALSO means the NON-Pro iPhone 11 has the single most-important enhancement to the 2019 iPhone family ! ... i.e., an Extra GB of DRAM relative to the XR.
The runner-ups (which BTW, NONE of the Apple-oriented OR tech websites mentioned at ALL today):
● The 100% Focus Pixels in the upgraded Back Wide-Angle image sensor !
● The (sophisticated) Clock Gating in the A13 !
