Hacking How do I know what version my R4i Gold is on?

[GoldenSun3DS]

The people I bought it from (nds-card.com), pre-loaded the firmware onto the MicroSD I bought from them.
The only problem is, I don't know which version it is.

I uploaded the contents of my MicroSD here: http://efshare.com/?s=R3SFHN (password to the archive is "123" without the quotation marks) (also it's less than 2MB because I only uploaded what was already there when I got it. I didn't put my roms or my homebrew on it, for example)

Can anyone determine from that what version my R4i is on?

And if it's not the latest version, how would I update it?

What's the website on the sticker of your card?
All r4i gold have been pre-flashed to support the latest 3DS 5.1.0-11.

My flash card works fine (DS games, homebrew, etc) on my 3DS (which is on the latest US system menu).
I just want to know what version my flashcard is on, and how to update it if it's not the latest version...

Also, I don't have my card with me right now as I gave it and my 3DS to my brother tonight. I won't have it back until tomorrow morning.
