good morning and in case i don't see ya' good afternoon and goodnight ....

so as i said in the title i have an iPhone 4 on firmware 4.3.3 and bb 01.59 and i want to upgrade to ios 5 i know that i must use snowbreeze or redsnow to preserve the baseband but the question here folks is do i need the official sim carrier to activate the iPhone later or i wont need it , i dont realy bother to have a tethered jailbreak anyway and i also wanna ask if somebody have tried this because now i'm aboard and i cant get my hands on the offical carrier sim in case you need to know the official carrier is pelephone (israel)


thanks in advance
