Yes they are still shipping (or at least mine arrived with .04.04 FW.)
As far as upgrading, steps were simple and easy (thanks to the talented individuals here)
1) Put Backup GEL file on Thumb Drive (Rename it to correct name)
2) Put in Scope and do FW upgrade
3) Save files Off of Thumb Drive to PC, and Put Hack FW on ThumbDrive
4) Put in Scope and do FW upgrade
I can confirm that the CHEAPEST model 5072 can be hacked to 350Mhz 4 Channels, all Options Perm with the hack FW. I just wish they would give more of those "Optional" BNC covers for the AWG.
It should take you longer to Format the USB drive to FAT32 than it does to hack the scope
