My iPhone says it has 04.04.05_G firmware. what Baseband or Bootloader do I have?

I'm asking because I have the 1.1.4 firmware that sucks on a lot of the latest goodies so I want to downgrade to 1.1.3

the problem is that I don't know what my Baseband or Bootloader is.

can anyone help me out?

That 04.04.05_G is the baseband version. Your firmware is 114 if this is a new iPhone or unlocked with standard procedures, some people mix and match so you can never tell.

Its quite simple, all firmwares have corresponding baseband, ie 112 will have baseband 4.02, 113 will have baseband 4.03 and 114 will have baseband 4.04.

Regarding bootloader version, that depends on the origin of the phone and how its been unlocked for instance some people have unlocked using Ziphone by downgrading bootloader from 4.6 to 3.9, but leaving that aside all phones firmware 112 and above have bootloader 4.6. Before that they had bootloader 3.9. To find your bootloader you can check the serial number and match it to the date of manufacture, if its firmware 112 OTB and above its bootloader 4.6.

If you have an unlocked iPhone you can use this app called HWInfo which gives you your baseband and bootloader version. Its available at www.trejan.com/irepo/. You have to put that in your installer sources list to install the app.
