The iPhone 5 is coming in two hardware models to support 4G LTE networks in different regions.
Apple unveiled the iPhone 5 today and it supports indeed 4G LTE. Apple made a point in the presentation that LTE is a mess. On the iPhone 5 LTE page you can see which carriers are supported in which countries. There are two different iPhone 5 hardware models. The A1428 (GSM) works with AT&T, Bell, Rogers, Telus,
The iPhone 5 A1429 (CDMA) only works with Sprint, Verizon and KDDI. The iPhone 5 A1429 (GSM) works in Germany, United Kingdom, Australia, Japan, Korea, Hong Kong and Singapore. As you notice the Verizon iPhone 5 has the same hardware model number as the German Telekom one. Does that mean you can use 4G LTE, but not 3G in Germany with a Verizon phone? Or does it work? I guess we have to wait until the dust settles to find out which iPhone 5 is more global in terms of 4G LTE.
