Global Firmware versions of Lumia 920 and 820 are now listed on NaviFirm. We have earlier informed that RM 820 is AT&T while RM 821 is global version of Lumia 920. Similarly RM 824 is global version of Lumia 820 while RM 825 is AT&T version of Lumia 820. The AT&T version of Lumia 920 and 820 is still not listed on NaviFirm.
Lumia 920 and 820 global firmware variants are available for European countries, Hong kong, China, Thailand, Saudi Arabia and also for South Africa indicating sooner release of the devices in these regions. Good thing is that Lumia 920 in Grey is also listed without any carrier branding for Thailand. So, may be it will come to Asian countries.
