With the alleged iPhone 5 release date allegedly coming Sept. 21 and the official announcement supposedly on Sept. 12, Apple junkies are anxious to find out as much about the specs of the new iPhone 5 before the phone's release. SmartPhone Medic took parts of the new Apple smartphone and put them up for display in video posted to YouTube on Wednesday.

The video looks at the black and white glass panel, 8-pin dock connector flex cable assembly, and two other flex cables. Justin from SmartPhone Medic took the opportunity to compare the new parts of the iPhone 5 to the iPhones 4s and Samsung Galaxy S3.

The first noticeable upgrade is the enlarged screen and smaller home button size of the new iPhone 5, claims Justin; other changes including switching the location of the camera and proximity sensor. Now the camera is above the speaker and the proximity sensor is next to the speaker.

The new screen for the iPhone 5 was also held up against the Samsung Galaxy S3. The iPhone 5 is still dwarfed by the massive size of the Galaxy S3.

The main flex cable in the iPhone 4s controls the headphone jack, the vibrator switch and the volume controls, according to Justin from SmartPhone Medic. In the iPhone 5, the flex cable no longer manages the headphone jack, but the sleep/wake button has been added to it, and the vibrator switch and volume controls stay in the same place.

The docking port flex cable in the 4s handles the home bottom, the microphone, 30-pin dock connector, a connector for the louder speaker, and docking port, claims Justin. The iPhone 5 docking port flex cable includes the service antenna, an 8-pin dock connector, and the headphone jack.

These changes mean that the headphone jack on the new iPhone will be located at the bottom of the phone, rather than the top. The headphone jack will also be where the liquid indicator is located, which was formerly in the docking port.

The dock connector's transition from 30-pin to 8-pin will have an impact on the phones docking ability. The new dock connector will be notably smaller, so older accessories may not be compatible with the phone.

The videos description notes that the people at SmartPhone Medic "haven't seen any signs of a liquid contact indicator for the top portion of the iPhone 5 yet." The new iPhone 5 will likely include one to prevent users from returning water damaged phones.

In another flex cable on display, the iPhone 4s's featured the sleep/wake button and a proximity sensor. On the iPhone 5's final flex cable there is a proximity sensor and noise cancelation microphone.

Gizmodo notes that the only major difference between the iPhone 4s and the new iPhone 5 from these parts is the screen size and docking port. The rest of the phones specs are the same, or in a different spot on the phone, like the headphone jack.

The SmartPhone Medic video was posted to YouTube the same day that it was reported that the iPhone 5 will be the first to feature 4G LTE in the United Kingdom. Everything Everywhere will be the UK's first ever 4G LTE network and will launch on Sept. 11.

On Tuesday German carrier Mobilcom Debite claimed the rumors of an iPhone 5 release date in September were true. "In September, it's finally time for a new generation of smartphone to go on sale," the carrier said on its website.

The editor-in-chief of iMore Rene Ritchie made claims of the iPhone release date in a statement back in July. "iMore has learned that Apple is planning to debut the new iPhone at a special event on Wednesday, September 12, 2012, with the release date to follow nine days later on Friday, Sept. 21. This information comes from sources that have proven accurate in the past."

Other parts believed to be included in the new Apple smartphone are a new camera opening on the back of the phone, and LED flash with a microphone, a unibody metal back instead of an all-glass façade that could improve reception, LTE connectivity support, NFC technologies for sharing content or sending money, multiplayer gaming, 3D photographing, and possibly even a "crack proof" screen.
