Custom rom? Is that how you were able to take screenshots?
There's a firmware update that been out for a while: 1600.3036.8853.12440
Firmware build 1600.3036.8853.12440 won't play nice with Bluetooth Share and DFT's BT File Transfer. Bluetooth Share keeps telling me to update firmware and BT File Transfer keeps crashing after app launch. Plus, WP7 Update Cab Sender keeps on getting installation errors after the first time sending the .cab file.
Either way, I already switched to RainbowMod 2.1 and abandoned my custom ROM. Even lucifer3006's ROM uses parts from the latest Nokia firmware and shows up as 8779. Don't think he'll ever fix it, as his thread for the ROM is now closed.
