Efectivamente esto es lo que dicen:
Around an hour ago the new version of the iPhone Operating System (now called ‘iOS’) was released.
iOS 4 is a huge release for Apple with many many changes and those changes offer slick additional features.
These new features are being offered by Apple as a free upgrade to qualifying devices.
We are working hard on a release to our tools that will jailbreak your device (or give you iOS 4 via the jailbreak train) and provide you with a carrier unlock.
Until these tools are released you should hold off on updating your device until we have
fully tested our tools with all the relevant devices.If you rely on hacktivation or a carrier unlock (ultrasn0w) then you should not upgrade until we have fully tested and released our tools.Don’t be tempted with unofficial PwnageTool/redsn0w bundles or releases, just check here or our
team twitterfor real time release information.
Remember, we risk our devices so
you don’t have to (but this time anyone who has made a mistake upgrading their baseband firmware at 3.1.3 or 4.0
should be OK
real soon Now!
