Honest question, no flames please? IPSF or iUnlock?
I know both methods cannot upgrade to 1.1.1 and work to make calls, but after reading around it appears that IPSF may be a 'safer' method as people downgrading from 1.1.1 with an IPSF unlock still keeps its IMEI (and if not they can fix it somehow) thus allowing me warranty service.
I don't know how IPSF is able to do it, a bit fishy really, though I'd rather spend $50 to protect a $350 purchase if it's worth it. I'm not particularly short on cash and will likely also donate $50 to this cause. I need an unlock due to excessive international travel and being able to swap SIMs on the fly is a key issue for me and I'm not that flush with cash to pay ATT for their international plan.
Thanks for any honest opinions. Cheers.
