Sony Ericsson recently added a new section to their developer world portal called Unlocking the boot loader. They provide all the information and tools needed to root some of their newer Android phones.

Of course, this information comes from Sony Ericsson dripping with warnings, disclaimers and warranty-voiding rhetoric. Once you’ve waded through all of that, you’ll have to enter your phone’s IMEI number, your name and email address in order to get your phone’s unique bootloader unlock key. Here’s hoping they don’t use the form information to instantly void warranties.

Unlocking doesn’t come without consequences, but from UI tweaks and performance improvements to custom apps and tethering, there are probably more reasons to unlock your Android device than there are reasons to leave it alone. In an age where people are making a fuss about companies adding stumbling blocks for would-be jailbreakers, it’s good to see that at least one of them is doing what they can to help hackers take the plunge. Anyone want to clear up why Sony Ericsson feels like supporting hackers but Sony sues people for doing similar things on the ps3?

The g2 has finally been rooted. Even though a temporary root exploit was found shortly after the phones release, a NAND lock prevented modifying the non-volatile RAM for a permanent root. Some controversy surrounded the g2 when it was erroneously thought to have a rootkit protecting the OS.  Supposedly the rootkit would watch for changes to the file system and then reset the phone to default settings when any unauthorized changes were made.  On the other hand a NAND lock functions by fooling the operating system into thinking there isn’t any memory available, essentially “locking” the memory in key areas.  Once it was discovered to have the NAND lock it was only a matter of time before the g2 was permanently rooted.  NAND locks have become a popular (and unsuccessful) deterrent employed by device makers to stop the jailbreaking comunity.  While this exploit is nothing groundbreaking it is another notch in the belt for the jailbreaking community and a welcome benefit to g2 users.

The iPhone dev-team has released an updated version of PwnageTool. It supports jailbreaking iPhones using the 3.0 firmware. This update does not include the much easier to use QuickPwn, but it should be coming soon. The release also doesn’t include the UltraSn0w unlock which will be coming via Cydia.

To appease people waiting for the iPhone 3G unlock, iphone-dev team member [MuscleNerd] did a live video demo this afternoon. The video shows him removing the AT&T SIM and putting in a T-Mobile SIM. After the switch, the phone shows no connectivity. He then runs “yellosn0w” in an SSH session with the phone. The phone then unlocks without needing to be rebooted and the signal bars appear. The final test shows the phone receiving a call.

The target for this release is New Year’s Eve and it doesn’t support the most recent baseband. Well be attending the 25C3 talk hosted by [MuscleNerd] and other team members. The VNC screen you see in the video is thanks to [saurik]‘s Veency.

iPhone dev team is at it again. They claim to have finally hacked the iPhone 3G. Originally codenamed “yellowsn0w”, it is targeted to be released on December 31st. This should free you from your locked in carrier as long as you have version 2.11.07 or earlier.

Google has new program to sell Android phones directly to developers. The Android Dev Phone 1 is both SIM-unlocked and hardware-unlocked. SIM-unlocked means you can use it on any GSM carrier you want. Hardware-unlocked means you can run any system you want on the phone, not just officially signed ones. No more need to worry about security patches taking away your root access.

The device is $399. You will need to purchase it through the Android Market as a registered developer (a $25 fee). We wonder how long before the unsigned bootloader starts getting flashed to T-Mobile phones.

Two new Android phones have surfaced recently which may prove just as friendly: the Kogan Agora Pro and the QiGi i6.

UPDATE: While shipping is free in US, it is incredibly expensive everywhere else. Yes, we bought one.

Working as quick as ever, the iphone-dev team have updated the PwnageTool and QuickPwn to work with the new iPhone 2.2 firmware update. The trouble with the new firmware is that it updates the baseband of the phone, which could potentially undo any progress made towards an iPhone 3G unlock in the future. If you don’t care about that, you can use QuickPwn to jailbreak your phone after the upgrade, so you can run any app you want. If a future unlock is important to you, use the PwnageTool to strip the baseband update out of the firmware update.

The iphone-dev team has officially stated “all that remains is implementation“. They’ve developed all the pieces they need to perform a software unlock for the iPhone 3G, now it’s just a matter of putting them together in user friendly fashion. They’ve managed to run unsigned code on the baseband, developed custom AT tools, and are now showing injection of a background task. They will combine all of these techniques to override the carrier lock baseband code. As usual, they warn against performing any official firmware updates to the phone.
