Upgrading a second-hand wizard

[Aviv]

I bought a wizard from a guy who got it from T-mobile US, so it's a T-mobile branded wizard. I want to upgrade my ROM version, so I read the guide and it says that I should do some steps untill I my spl and ipl are 2.26. My wizard's spl and ipl are 2.26 already (gsm02.25.11, os2.26.10.2) so I want to know if i'm ready to upgrade my ROM without a CID unlock and downgrading to 1.05 ROM (That guy may have done that, but I don't have a clue...)
Thanks.

Since you don't have a clue, then you need to carry on reading.

There are threads in here about CID unlocking, and also in the wiki (links at the top of the page).

It's better to understand what you are asking for help on if you can't follow the instructions, than to follow someone blindly in case you miss a step they assumed you knew.

It's an expensive device to brick if you don't know what you're tring to do.

I'll second that opinion!
