New iPod Touch isnt as good as presumed?

There are news that the new iPod touch 4G doesnt hold what he promised:

• According to the iFixit teardown the iPod Touch 4G has exactly the same marking as the iPad processor. This means that there is only 256 MB of RAM.
• The camera found in the rear, can only shoot photos with 960x640 resolution. That is about 0.7 Megapixel (the iPhone 4 has 5.0 MP). The front camera is almost identical.
• No vibrator! On the Apple website it said that the iPod Touch 4G had a vibrator to respond to FaceTime calls. Later the website was edited and the line removed. iFixit didnt find any vibrator in the iPod Touch.

Read the whole teardown at iFixit.com.

What is tethered and untethered?

If a jailbreak is tethered, you have to connect to the computer once you reboot to rejailbreak.
If a jailbreak is untetherd, you can reboot without having to connect to a computer.

redsn0w, untethered
sn0wbreeze, untethered

New Bootroom jailbreak?

There are rumours going around the internet that there will be a new bootroom jailbreak for all iOS devices.

A bootroom jailbreak is a jailbreak that you have to do with your device powered off, for example redsn0w. A userland jailbreak is a jailbreak with the device on like Spirit or Star (jailbreakme.com).
The exploit was found on the day iOS 4.1 was released by p0sixninja and pod2g.

The good thing about this exploit is that it works on all devices and will support all future firmwares. To patch this exploit, Apple will need to make hardware modifications.

It is yet unknown if this jailbreak is tethered or untethered (What is tethered and untethered?).
