Before this dev-team has already demonstrated iPhone OS 4.0 jailbreak and GeoHot come up with iPad 3.2 jailbreak with Blackra1n as well. (image via GeoHot)

As the new jailbreak tools are expected soon, Apple won’t sit idle and will bring a new firmware update to fix those exploits used in the jailbreak, so it’s best time to grab your ECID SHSH on file to secure your future jailbreak. Use the guides linked below to grab SHSH for iPhone 3GS, iPod Touch 3G, iPod Touch 2G (MC) and iPad 3.2 as well.

Apple announced iPhone OS 4.0 which came with 100+ new features including Multitasking, iBooks, Game Center, Unified Mailbox and many more. Checkout the complete list of iPhone OS 4.0 Features, complete iPhone OS 4.0 coverage, Keynote and also iPhone OS 4.0 videos & gallery..

Stay Tuned.. More in coming on iPhone firmware 4.0.

I have locked iPhone 3gs 3.1.3 BB 01.05.012, so if I upgrade it to 4.0, CAN I jailbreak it????

No, You can’t, but GeoHot can. 🙂
The meaning of the post is the following; if nothing is changed in official OS 4.0 (compared to this beta version) GeoHot will be able to provide us jailbreak oportunity in a short time. If Apple changes something, then jailbreak might be harder (or, impossible in worst case scenario) to implement (we hope not).
That’s the reason why there is no untethered jailbreak for OS 3.1.2 and 3.1.3 (so that GeoHot doesn’t give a clue to Apple how to prevent (or make harder) jailbreak on major OS upgrade like 4.0).

Because both Bla, Bla, Bla and not give us a solution to the problem of baseband 05.12.01. Both Geohot as dev-team and more MuscleNerd only criticize one another and do nothing. Accept that Apple will win this time. Enough donations.
