The people over at ZiPhone spotted some code in the brand new 2.0 beta iPhone firmware that could point to the chip to be used in the upcoming 3G iPhone.

The code makes mention of ‘SGOLD3,” which could very well refer to Infineon’s followup chip to the S-GOLD2 which powers the current iPhone.

Infineon’s other name for the S-GOLD3H chip is the PMB8878, a 7.2Mbps HSDPA chip with all the video acceleration and media playback features iPhone users have come to expect.

Some features include higher resolution camera support (5 megapixels instead of our current 2), a 2X speed MMC / SD interface and more. However, that doesn’t mean any of these specs will end up in the iPhone 3G, but it is capable, leaving our minds souring as to what will come for the next iPhone.

Stay tuned…
