The recent good news constantly, A5 chip untetheredjailbreak made good progress, and many locked users concerned baseband 04.11.08 and 02.10.04 unlock also news. The well-known iPhone hacker Sherif Hashim has just confirmed that he is still working very hard to unlock iPhone4 02.10.04 baseband (on iOS 4.1) and 04.11.08 baseband (iOS 5.x).
If you are an iPhone user stuck on high basebands which neither can be unlocked by Gevey SIM nor Ultrasn0w, don’t worry anymore. In case you want to upgrade to iOS 5.0.1 without upgrading your iPhone 4baseband to 04.11.08, you’ll need to preserver your iPhone baseband.
Here’s what Sherif Hashim said about the iPhone 4 GSM unlock:
for those whom are still concerned YES i am still working on the VERY TIGHT bbfw 2.10-4.11 (i m taking that personal) after my -October 2010 found- vulnerabilities failed to achieve a payload injection vector despite the huge continuous trials and work done by the legendary @MuscleNerd, the great everlasting iOS hacker and guru, keeping in mind that there was a 10 months of halt due to the Egyptian revolution , what I meant to say is that any new achievements -IF EVER POSSIBLE- regarding this issue will be notified either by this respectable iOS hacker or by the humble myself, NO NEED to ask because it won’t make it achievable/earlier/easier. Thanks a lot for taking time to read this.
