After further examination, we found a way to open the logic board without completely destroying it.

Samsung chip underneath the metal shield on the left side of the board on the left. Ours reads K9MCGD8U5M. The 4 GB model that Think Secret took apart had K9HBG08U1M on it, which is a 4 GB chip

Samsung memory stacked with a 620 MHz ARM architecture processor, ARM1176JZF. Could be a Samsung S3C6400. Numbers: 339S0030ARM, 8900B 0719, NOD4BZ02, K4X1G153PC-XGC3, ECC457Q3 716. The processor is likely stacked on the SDRAM, which could be two 512 Megabit chips. The processor could have H.264 and MP3 hardware decoding built in.

The chip above the ARM is a Wolfson audio chip. Part numbers WM8758BG and 73AFMN5.

The chip underneath the ARM is a Linear Technology 4066 USB Power Li-Ion Battery Charger, which Apple uses in the iPods as well.

The chip on the bottom center that looks blank in our image actually has this text: MARVELL, W8686B13, 702AUUP. This is Marvell's 802.11b/g 18.4mm2 chip.

The chip in the upper right is a Skyworks GSM/Edge Power amplifier (SKY77340).

The silver chip to the left of the Skyworks chip reads CSR 41814 3A06U K715FB. This is a CSR BlueCore4-ROM WLCSP single chip radio and baseband IC for Bluetooth 2+EDR.

The chip covered by the white sticker in the photo has the part numbers 338S0289 and 8G60710 on it. EETimes claims this is an Infineon M1817A11.

The chip with the blue dot on it is rumored to be an Intel Wireless Flash stacked 32 Mb NOR + 16 Mb SRAM chip. Part numbers 1030W0YTQ2, 5716A673, and Z717074A. EE Times adds the part #PF38F1030W0YTQ2.

The chip in the lower right reads 338S 0297 G0719. Some claim this is an Apple-branded chip, but it's purpose is currently unknown.

The chip in the lower left is an Infineon PMB8876 S-Gold 2 multimedia engine. Part numbers: 337S3235, 60708, and EL629058S03.
