  • Just kidding. Look, the battery isn't soldered on!

  • Apple actually listens to us! Or something.

  • Dock and headphone connector.

  • The primary antenna is on the other side of this part.

  • Once we get the phone completely apart, we'll start posting chip numbers. We'd love help identifying chips from all of you, send us any inside information to iphone3g@ifixit.com. We'll keep it anonymous.

  • This is where we get excited! We've done our best to identify everything that's on the iPhone board.

  • Semiconductor Insights and TechOnline have released the almost-authoritative list of all substantial iPhone chips. They've graciously provided us with their images. We're going through and verifying their results now, but we expect that their accuracy will surpass our own.

  • So by our count, here's the chip counts by manufacturer (more important chips are bold):

    • Broadcom 1, Infineon 4, Intel 1, Linear Technology 1, Marvell 1, National Semi 1, NXP 1, Samsung 1, Skyworks 1, SST 1, ST Micro 1, Toshiba 1, Triquint 3 (big win!), Wolfson 1.

    • Our list undoubtably omits a number of components. Don't freak out if the chip you spent years slaving over isn't mentioned, please! We're happy to update it if you let us know.

  • And Marvell for the win on the CSR BlueCore Bluetooth + WiFi. This is the same chip as the iPod Touch and first iPhone.

  • Toshiba manufactured the flash in both iPhone logic boards we've seen so far. We'll see if this trend holds.

  • Intel NOR flash in the middle left of the shot: 3050M0Y0CE 5818A456.

  • The largest chip in the top left corner is an Infineon 337S3394 WEDGE baseband marked SP836175 G0822.

  • Small chip to the right of the NOR: Infineon BGA736 (Tri-Band HSDPA LNA). Just beneath that is an Infineon UMTS Transceiver marked 338S03532Z 60814.

  • Skyworks power amplifier SKY77340 (Power Amplifier Module Quad) on the top right: Octopart datasheet

  • The chip in the top middle is SMP 3i 6820, Infineon SM-Power3i. From Infineon: the part is "optimized to support modem and data card applications based upon X-GOLD208 and X-GOLD 608, with features ranging from EDGE up to 3G and HSDPA."

  • Chips we need to identify: 6475 with M logo (rumored to be Murata IF SAW Filter).

  • The entire board (the EMI shield is removed from the right side).

  • The previous shot is the top right portion of this picture.

  • Removing the EMI shielding is tricky, so we're taking our time.

  • If you'd like to comment publicly, use the Gizmodo forums or reply via twitter to ifixit, and Summize will pull it up.

  • The other half of the board. Note the Apple-branded ARM on the left and the SIM card holder at bottom center

  • Big news: Samsung DDR SRAM markers on the processor again. Looks like they win on the processor front again (not that we were expecting anything different).

    • Processor markers: 339S0036 ARM EMC567DB 819 8900B N182F0A3 0825 7511.101 ZPD8163Y, 5974V CKUFBG HE0819 870628 P12 N3. Samsung DDR on the chip (K4X1G163PC-DGC3) is slightly different from the first iPhone, which was K4X1G153PC.

  • SST SST25VF040B 1MB SPI Serial Flash to the left of the SIM card, along with a National Semiconductor LM2512AA Display Interface.

  • APPLE 338S0506 is a Wolfson WM6180C (We haven't seen Wolfson disguise their chips like this before). APPLE 338S0512 is an obfuscated NXP power management chip.

  • The GPS chip is the grey chip in the middle-right side of the board. It is an Infineon PBM2525 Hammerhead II! Rumors that it would be integrated into the processor have been disproved

  • The round grey chip to the right of the Apple-logo processor is the ST Micro LIS331 DL Accelerometer.

  • The back of the logic board, after pulling up the metallic shielding.
