Upgrading to 1.1.3 with bad seczone
I did some stupid things when i was supposed to revirginize my iphones seczone and so on a couple of months ago so i lost my RSA token. And someone told me it might be so that i can't update to later updates because of it (http://www.hackint0sh.org/forum/showthread.php?t=12626). My phone is 1.1.1 now and i wonder if anyone can tell me if it's safe to upgrade to 1.1.3 anyway or if it bricks it because of my stupidity while updating to 1.1.1?
Btw, if i upgrade to 1.1.3 i won't lose my unlock right?
