Hi, my name is Janice and I have an iphone4 but am technically a dullard. I am trying desperately to set up my phone so that I can block numbers from both texting and phoning. My phone is Version 4.1, modem firmware 02.10.04. From what I can gather from other threads, there is not software available yet to jailbreak this version of the iphone4? Can anyone confirm that for me please? I am in Australia and our providers to not offer this facility as they apparently do in the US. I paid for some software a couple of months ago to do this, but am confused as to whether it'll actually work on my version phone. I'm also scared that I'll stuff up my phone if I try, as I've heard some reports that it can do this. Can anyone help?? Thank you!!!
