[* black] Infineon 337S3754 [http://www.infineon.com/cms/en/product/channel.html?channel=ff80808112ab681d0112ab6ab94205ef|PMB 8878 X-Gold baseband IC] 5Y06115. This part had the Infineon logo in the pre-production unit, but Apple has white-labeled it to obscure the manufacturer. This is the exact same baseband processor as the iPhone 3GS.

[* black] Along the right are three TriQuint power amplifiers: TQM616035A, TQM666032B, and TQM676031A. These are the same three chips that Apple used in the [guide|600|iPhone 3G nearly 2 years ago|stepid=3194].
