Really? I didn't realise that, I thought it had to be AT&T...
No, if you compare the specs between AT&T and Verizon, the non-LTE specs are identical. My question is whether a Verizon model will support an AT&T sim, so that if LTE for Verizon is unavaliable, you'd revert to AT&T 3G, instead of Verizon's slower EV-DO.
From Apples's website:
"It also works on GSM/UMTS worldwide network technologies including HSPA, HSPA+, and DC-HSDPA — the fastest 3G networks out there. You’ll see downlink speeds up to 42 Mbps with DC-HSDPA and up to 21.1 Mbps with HSPA+.3"
"Wi-Fi + 4G for AT&T model: 4G LTE (700, 2100 MHz)3; UMTS/HSPA/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz)
Wi-Fi + 4G for Verizon model: 4G LTE (700 MHz)3; CDMA EV-DO Rev. A (800, 1900 MHz); UMTS/HSPA/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz) "
