An earlier report and a product description from Apple stated that the iPod touch 4G would receive vibration alerts for FaceTime calls. Apple today updated their site to remove references to vibration and it seems that TouchFans misidentified the microphone as the vibration motor.
● The battery lists a capacity of 3.44 Watt-hours.
● The fourth generation Touch's rear-facing camera does not support autofocus and is a much lower resolution
● The new iPod Touch includes only 256 MB of RAM
● This iPod features the same A4 processor that's found in the iPad and iPhone 4
● The iPod Touch now has a legitimate speaker
iPod Touch 4th Generation Repairability: 4 out of 10 (10 is easiest to repair)
● Good: Opening the device is pretty straightforward, as long as you have a heat gun and some iPod Touch opening tools handy.
● Good: The headphone jack is not soldered to the logic board, a first for the iPod Touch line.
● Bad: The front glass and LCD are permanently fused together, increasing the cost of repairing broken front glass.
● Bad: Removing the display completely requires removing the logic board
● Bad: Apple soldered the volume button and sleep button cable to the logic board. The previous Touch had a ZIF connector. This makes removing logic board very difficult.
● Bad: The battery is still soldered to the logic board, just like previous models.
