Firmware 3.0 Beta may block iPhone
This is an important warning, as many venture into installing unauthorized copies of firmware released on the internet.
Yesterday, along with the SDK, Apple also released a beta version of firmware 3.0, exclusively for developers enrolled in its Program Dev (and pay an annuity).
Obviously, the example of last year, some copies of this beta fell on the network and many are venturing to install it on the iPhone itself. What they do not know is that may be blocking your phone indefinitely.
It happens that Apple blocks by the use of beta unique identification (UID) of the apparatus. With that, who is not enrolled in the official program can not run the system, blocking the fateful phone screen USB cable.
"But there's no problem, just restore to 2.2.1, right?" WRONG!
Once installed, the device is locked in "test mode", no longer allowing the installation of any firmware prior to it.
The Dev-Team said yesterday that the jailbreak firmware 3.0 is still possible, but gave no date for it to become effective. This means that those who install the beta downloaded unofficially, will run the device is locked, no predictions of solution.
So, do not venture downloading over the Internet to find, because this can cause you a headache ...
You can always go back to firmware 2.1.1 and jailbreak.
The trick is to put the iphone into DFU mode:
Step One
Open iTunes and connect the iPhone to your computer.
Step Two
Press and hold the Home button (button front) and the Sleep / Wake button (off) at the same time.
Step Three
After exactly 10 seconds release the Sleep / Wake button. Continue holding the home button, Until you iTunes pops up a message telling you That it has detected an iPhone in recovery mode.
NOTE ***: It may take a few attempts to get your iPhone into DFU mode. Generally, I hold Both buttons down then release the Home button just before I think the Apple logo would appear. If you are still holding Both buttons down and you see the Apple logo you are holding down for too long Them!
In order to do restore on iTunes and apply the jailbreak
WARNING: This is valid for Iphone 2G, 3G in the case of not risking the installation.
Firmware 3.0 on IPHONE 2G accepts only Yes AT & T which does not allow its use outside the USA or another operator (no jailbreak or debloquear sim)
