The folks 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 less fancy 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. Advantages over its predecessor include higher resolution camera support (5 megapixels instead of 2), a 2x speed MMC / SD interface and DVB-H module support, but that doesn't necessarily mean any of those specs will end up in the ensuing iPhone 3G -- S-GOLD2 has plenty of features the current iPhone doesn't take advantage of. The processor speed, however, remains the same.
