Noob question: how do I check my firmware?

[truenorth]

Just got a brand new iPhone. I tried to follow a YouTube video step-by-step procedure to unlock the iPhone but I cannot get the yellow triangle when I press the Sleep and Home buttons.

Could it be that my iPhone came with the 1.1.1? How do I even find out? I tried to do a search but can't find any thread or info.

Told you this is a noob question.

Thanks in advance.

You can check what firmware is preinstalled by going to the emergency call, entering *3001#12345#* then pressing "Call". Under Versions you will find what revision firmware is on the phone out of the box.

03.12.06_G Is firmware 1.0.0
03.14.08_G Is firmware 1.0.1 and 1.02
04.01.13_G Is 1.1.1
