Sherif Hashim Still Working On iPhone 4 Baseband 04.11.08 – 02.10.04 Unlock

Here are some good news for iPhone users who are stuck on high basebands which neither can be unlocked by Gevey SIM nor Ultrasn0w, the well-known expert iPhone baseband hacker Sherif Hashim has just confirmed that he is still working very hard to unlock iPhone 4 02.10.04 baseband (on iOS 4.1) and 04.11.08 baseband (iOS 5 / 5.0.1).

We don’t want to talk a lot so we’ll brief what Sherif Hashim said.
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

However, he asked users not to keep asking about the release and just wait:

NO NEED to ask because it won’t make it achievable/earlier/easier.

We conclude that status will be communicated by either him or by the legendary iPhone hacker MuscleNerd whenever the ultrasn0w unlock is available.
In case you want to upgrade to iOS 5.0.1 without upgrading your iPhone 4 baseband to 04.11.08, you’ll need to preserver your iPhone baseband. You can follow our guide posted here to preserve iPhone 4 baseband while upgrading to iOS 5.0.1 using redsn0w.
