Apple to resolve iPhone reception issue as soon as Monday with iOS 4.01

Invisible Shield for Apple iPhone 4!“Reception issues observed by new iPhone 4 owners, derided as the ‘Death Grip’ by bloggers, appears to actually be a software issue that an iOS update is expected to resolve early next week,” Daniel Eran Dilger reprots for AppleInsider.

MacDailyNews Take: So, perhaps our source was right after all?

Dilger continues, “Readers report that Apple’s tech support forums originally confirmed that a iOS 4.0.1 software fix addressing the issue would ship early next week (as early as Monday), before the comments were subsequently taken down along with all the other related discussion about the matter.”

“The fix is expected to address a issue in iOS 4 related to radio frequency calibration of the baseband,” Dilger reports. “Readers who saw the original forum discussions say that the issue is believed to occur when switching frequencies; because the lag is allegedly not calibrated correctly, it results in the device reporting “no service” rather than switching to the frequency with the best signal to noise ratio.”

“iOS 4 introduced some enhancements to how the baseband selects which frequencies to use, so it makes sense that the error may have crept into those changes,” Dilger reports. “Additionally, this explains why iOS 4 has also caused similar problems for iPhone 3GS users.”

Dilger reports, “Additional readers have shared other related experiences that also corroborate the idea that the issue is related to iOS 4’s software control of the baseband, including the fact that the issue seems easily reproducible when connecting to a WWAN 3G network but does not appear when connecting to a Microcell 3G. If the problem were simply hardware related issues of the antenna design, it should only affect iPhone 4 units with that new design and should occur at all times, regardless of the tower type. That is not being observed.”

MacDailyNews Take: We reported on Thursday, June 24: “According to a trusted source, there are multiple points on the iPhone 4’s frame for antenna reception. Our source says that the issues ‘can and will’ be addressed by tweaking, balancing, and/or redistributing antennae reception and/or signal strength display via software. When asked if it could be a hardware issue, our source said, ‘Don’t be silly. It’s not the hardware. Apple’s too smart for that. In fact, most any handset maker is too smart for that.'”

Maybe Steve Jobs’ “Just avoid holding it in that way” email reply was meant to be a joke that nobody got?

  1. Of course, I’m still gonna buy one. I’ll just have to watch how I hold it when my hands are sweaty ” width=”19″ height=”19″ alt=”smile” style=”border:0;” />

  2. I have noticed problems with my 3GS since updating.
    I was thinking they had changed something to reserve more battery power and now will have to turn it back up (pre-amp?).

  3. No problems with iOS 4 on my 3GS. I’ve been using the GM for a few weeks now and it’s been rock solid.

    My only complaint is with multitasking, I wish there was a limit to the number of Apps you have open (so i can set, for example, a maximum of 5 Apps to be open at any one time).

    If I use my iphone for a few hours, I double click the Home Screen and I have pages and pages of open Apps. Why does the Clock need to be running in the background?

    Other than that (which I’m sure Apple will come up with a great solution for) I think iOS 4 has finally caught up with Windows Phone 7 ” width=”19″ height=”19″ alt=”grin” style=”border:0;” />

  4. MDN , then you should have stuck with your “trustworthy source” and quit spreading your gizmodo style hatred a couple of days ago until apple put out an oficial statement. Not some email that no one can prove it’s even real.

  5. @ Cannon20,

    Sounds like a non-functioning or malfunctioning proximity detector… Which I read has been noted in a few forums.

    Try making a call, and lay your index finger across the whole earpiece section of the phone… Does the display turn off? It should; if not, then your proximity detection isn’t doing its job – turning off the display and disabling the touch screen.
