carrier-explode iOS carrier and country bundles

Verizon

Verizon’s main bundle is Verizon_LTE_US 72.0.1. The _LTE_ is left over from the switch away from CDMA; the CDMA-era bundle was Zeppelin_US, and Verizon’s CDMA carrier ID 310VZW still points at it in the manifest.

                    311480_GID2-A8, 310599_GID2-A8, 310590_GID2-A8

In the manifest, Visible is GID2 1A, Xfinity Mobile A3, Spectrum Mobile A7 and Verizon Response 1B, all with ICCIDs starting 891480. These same SIMs are also listed under Vodafone Netherlands’ 20404; see Bundle Selection § Shared IMSI ranges.
