The Wall Street Journal’s article focusses mainly on the fact that the new iPhone would work on a type of wireless network called CDMA,s suggest that US phone giant Verizon would support the iPhone and end AT&T’s American iPhone monopoly.

But as soon as WSJ’s article was posted around the internet, more rumours and speculation began to emerge. Engadget notes that the iPhone 4G’s arrival wouldn’t be a big shock for Apple fans, writing “if the Cupertino-based company keeps with its historical refresh pattern, we’re just a few months out from seeing the latest and greatest iPhone.”

The gadget news website said it was informed that the fourth generation device would be announced on June 22nd and is set to be named the iPhone HD on account of its high resolution screen.

Technology pundit John Gruber coroborated this revelation, saying the new device will sport a 960×640 display. The current iPhone display is 320×480, which is quite low compared to rival smartphones such as the Windows Phone 7 Series, which boasts a 800×480 screen.

Gruber’s other tidbits, presented alongside his assessment that WSJ’s entry into the iPhone 4G rumours game was “lame”, included the A4-family CPU system-on-a-chip (similar to the iPad’s processor), a front-facing camera and third-party multitasking.

The video description says, “We have seen this assembly online before but when a very reliable source showed us that they had one we had to get it”. The description continues “Of course we can’t 100% guarantee that this will be the design for the iPhone 4G our sources are very confident that not much, if anything will change.”

Shown against the 3G’s fascia, the new screen is slightly longer and has a new hole next to the external speaker, presumably for the rumoured front-facing camera.
