Apple’s iOS 4.3 update hit yesterday and within hours, developers had found further evidence that Apple plans to use its dual-core A5 processor in the next-generation iPhone.

Per iClarified, developers have found references to the A5 processor in a kernel file for a device codenamed N94AP, widely assumed to be the iPhone 5, within the code for iOS 4.3 (full picture available here).

According to the report, the A5 chip is referred to as S5L8940 in the iOS 4.3 code and, as expected, is also listed as the processor for the Wi-Fi, GSM and CDMA versions of the iPad 2.

Apple released iOS 4.3 on Wednesday, ahead of Friday’s iPad 2 launch and two days earlier than originally expected. The software update improves JavaScript performance in the mobile Safari web browser, features third-party support for AirPlay wireless streaming and adds the Personal Hotspot feature first introduced on the Verizon CDMA iPhone 4 in February.

Apple took the wraps off the new A5 processor last week when it unveiled the faster, thinner and lighter iPad 2. A recent rumor suggested that Apple has turned to Taiwan Semiconductor Manufacturing Co. to produce the A5 chip, rather than staying with Samsung, its original partner for the A4 processor.

Stay tuned for additional details as they become available.
