  • Possible fix for reception issues?


    Some crazy (read: awesome) fellow over at [ame=http://forums.macrumors.com/showthread.php?t=955742]MacRumors[/ame] may have accidentally run into the real cause of the so dreaded reception issue that has been plaguing the iPhone 4. The benefit of finding the cause is that the solution is so simple I'm still having trouble believing until I tried it myself.

    It actually worked.

    For those that can't be bothered to click or links or have the attention span of a cat on caffeine, here's the summary:

    After taking my sim card out to test this I inspected it closer for the first time.

    The metal part of the sim card is not centered and is contacting the sim tray. The sim tray is steel and the sim tray is contacting the outer antenna band. Once you touch the phone, this could be causing a sim issue.

    If when you touch the antenna line on the lower left it changes the state of frequency, power or what ever, it might actually be messing with the sim card.

    The metal on the sim is connected to the sim tray, the sim tray is connected to the antenae and the antenae is connected to your hand when you touch the phone.

    Take a look at your sim card and see if the metal is just off center enough to touch the tray. This might be so simple it's stupid nobody has thought of this.
    The general result from people posting there have been positive. "Fixing" this issue however can be tricky for some. As everyone knows, iPhone 4 runs a Micro SIM card, and the tray is designed as such that you really have no wiggle space to reposition it in order to avoid the sim memory to touch the tray. I personally used tape and it worked. Others have taken different approaches to the issue (cutting, coating, sacrificial goat), but the goal is the same: Don't let the sim memory (gold contacts) touch the tray!

    NOTE: Of course you can still death palm it and get the signal to fail, this is more directed at those users that have signal issues just by covering the slit with their finger, etc. There seems to be mixed results, maybe it does something, maybe it doesn't.

    Feel free to post your results here.
