4G iPhone Contains Hidden A4 Microprocessor

Recent leaks featuring the latest 4G iPhone images have surfaced, showcasing detailed views of its internal components. Notably, these images include a clear view of what appears to be Apple’s A4 processor.

Engadget highlights the presence of “339S0084” just beneath the Apple logo, confirming the processor’s identity as the A4, according to Chipworks.

The A4 chip, an Apple-designed system-on-a-chip (SoC), is manufactured by Samsung and is also utilized in the iPad. Users often praise the iPad for its quick and fluid performance.
