There have been no official complete stock packages since DL09. You can get newer ROMs to flash in ODIN, but the newer modems are only available with CWM. But if you have CWM, you are not stock! You'll need to ODIN the DL09 ROM/Kernel/Modem package to get completely stock and then you can OTA to ED04 if you want. If you flash just an ED03 ROM, your modem will not match and Verizon may see that and know you were not stock! Also, the ED05 that came out is complete and ODIN capable, but don't flash that because it is not "official".
FYI, I changed phones without thinking about this and have to return my old phone with DL09. I forgot to OTA before activating my replacement Droid Charge. I could call Verizon to have them reactivate the old phone, but that would be hard to explain. And I don't want to risk losing the 4G unlimited package by switching back and forth. So, I'm sending it back with DL09 stock. I'll play dumb if they bring it up, but I doubt they would.
