Verizon iPhone 4 teardown reveals Qualcomm ‘world phone’ chip, new antenna design, and more

“We got our hands on the new iPhone 4 Verizon on the morning of February 7th, 2011,” iFixit reports.

Notes:

• The SIM slot is gone. According to Apple, the SIM card and SIM tray were the only user-serviceable parts in the AT&T iPhone 4. Apple now says “iPhone does not contain any user-serviceable parts.”

• We believe the additional break in the antenna enclosure on the right side of the phone is a result of the switch from GSM to CDMA. An antenna’s operating frequency is directly dependent on its size and geometry, so the change-up required an antenna overhaul.

• Apple has removed the counterweighted vibrator motor in the corner of the phone and switched to a different vibrator design that’s now placed near the battery connector. The iPhone 4’s vibrator received a complete makeover. Rather than using a rotational electric motor with a counterweight, the Verizon iPhone appears to utilize a linear oscillating vibrator for call/message alerts. Our tests show that the new vibrator has quieter, softer feel, and makes a better sound when on a table.

• The Qualcomm MDM6600 chip supports HSPA+ data rates of up to 14.4 Mbps and CDMA2000® 1xEV-DO Rev. A/Rev. B. It supports both GSM and CDMA—which means that Apple could have supported GSM!
Why didn’t they? It may be that it was easier to design antennas for a CDMA-only phone — this phone supports two cellular frequency bands, while Apple supports five bands in the GSM version. Of course, there’s no way it could be a real “world phone” without a SIM card slot.

  1. APPLE!!!!!, why did you not create a world phone.

    I am trapped on Verizon blackberry. We do heavy international travel, and are just now looking at other smart phones.

    I am going to be taken to Android crap because APPLE doesn’t support international travel requirements.

  2. @chaz,

    You ignorant slut. Apple DOES create a world phone, how else do you suppose iPhones are sold GLOBALLY?

    C’mon, I mean, how stupid are you? Just because you CHOOSE to be limited to Verizon’s bass ackward network (one that can’t even do the basics- Voice and data? Bueller?).

    Verizon minus SIM minus voice and data- How 1980’s!

  3. @Chaz,
    “APPLE!!!!!, why did you not create a world phone.”

    Please. !!!! And there is NO anti-gravity and no warp drive either…. What was Apple thinking. ?? ” width=”19″ height=”19″ alt=”grin” style=”border:0;” />
