iBEC and iBSS can they change?

[xultar]

Question I grabbed my iBEC and iBSS before I did all the sync and stuff on my new 3GS. I used the sim from my old 3g so it was activated. But, basically I set it up as a new phone and didn't bother with syncing because it takes so long to load my apps and music.

Am I good? Or do I have to do the iBEC and iBSS grab again.
