Ok people, after over 2 years of being a loyal non JB or unlocked iphone user I gave up with O2 and unlocked my phone (they wouldn't do it despite me being out of contract). Anyway...my question is this. While I can use any sim, I would really like to have the IPPC file for vodafone on my phone. How do I get this file and how do I install it on my phone? Thanks in advance.
