WP 7.8 (Build: 8858) For Lumia 900 Now Available on Navifirm

| December 14, 2012 | 2 Replies

Yesterday both the Lumia 510 and the 800 had their WP 7.8 FW released on navifirm, now the Lumia 900 joins the group coming with the finalized WP 7.8 version number (8858). The leaked version is only for Rm-823, which is the global variant and not the At&t version, so anyone on At&t hold you horses and don’t do anything you’ll regret.
