The fourth generation of iPod touch will be released the week after official listing, so currently there is no opportunity to see its true capacity for the vast majority of consumers, and the dismantling unveils. But thanks for the FCC (Federal Communications), According to the provisions, their wireless networking products must pass the test, and publish the test report before listing in market in the United States. Today, the test report of the new iPod touch appeared in the FCC Web site, even including a clear picture of the dismantling. 
The fourth-generation iPod touch is called as the sister of iPhone 4, there are too many similarities in the specifications of configuration. Here we have summarized the differences between them:
In Function, iPod touch can certainly not support first to support WCDMA / GSM mobile phone network, so calls can not be achieved. And it is no built-in GPS and digital compass, also no close transducer. Although they have the same Retina Display LCD screen of 960x640 resolution, the iPod touch are not of IPS panels. The main camera can shoot 720p video, but the camera resolution is only 960x720, far less than iPhone 4 which is of 500 million pixels, and is not configured LED flash.
In Appearance of the configuration, the difference between the two is that: iPod touch is covered by stainless steel, the whole thickness is thinner (iPod touch 7.2mm, iPhone 4 9.3mm). The top of the front fuselage isn’t of the handset, so VGA video call camera must located in the center. Bottom of the fuselage of the built-in speaker is only one opening, comeing with wireless controller and headset microphone features.
According the Photos provided by FCC, we can find iPod touch model is A1367, and the clear distinction to iPhone 4 motherboard designation. The battery capacity is 3.44Whr, less than iPhone 4 of 5.25Whr capacity, but both of them has 40 hours of the nominal life time of music playback.
In addition, we can find by FCC test, the fourth-generation iPod touch if an engineering samples, and with slightly difference to Apple products announced today. For example, there is no built-in speaker openings at the bottom of the fuselage. Therefore, it isn’t ruled out that the final production design, there are other fine-tuning in final production designation.
