I bought my phone about 3 weeks ago, everything works fine. I stared to look around for some guides to change ringtones and so on, found one for iBrickr, pluged my phone , start iBrickr ,and everything was opened, no goofing around, wonderful. Now i started looking at upgrading it to 1.1.1, i have 1.0.2, but since i did not unlock it at the start i have no idea how it was done. Is it safe to follow the Ibrickr guide i see floating around ??? I am no expert but know my way around programming a little.

Thanks for the help

Upgrade to 1.1.1, if your phone is not bricked, it's used IPSF otherwise it's used anySim or iUnlock. Of course you can unbrick it.
* But before doing that: use nordump to save your baseband.
