I am using iTunes 7.3.2 with SW unlocked iPhone using iUnlock, is it safe to upgrade to iTunes 7.4.1?
If safe, should I need to restore it at iTunes 7.3.2, and then upgrade iTunes to 7.4.1, and then activate, jailbreak, and SW unlock my iPhone again?

Now:
iTunes 7.3.2
SW unlocked by iUnlock, iPhone FW1.0.2
iNdependence 1.1.1 activated and Jailbroken
YouTube working
Wifi working

Thanks for anyone can answer my question!!

no need to re unlock... just upgrade iTunes... as long as you have independence 1.1.1 you wont have any problems... people had problems jailbreaking there phones with iTunes 7.4.1 and older versions of independence....

Thanks a lot!!
I upgrade iTunes to 7.4.1, no problem with my SW unlocked iPhone.
