    Lightbulb [1st gen 2.0.2] Signal strenght workaround

    Hi all.

    I noticed today my 1st gen iPhone -- running 2.0.2 -- was getting weaker signals than last week, on the very same spot I sat here in the office.

    And I remembered this weekend, right after QuickPwn for Mac was released, I ran it just to have proper files on my phone -- I was one of the eager iPhone owners who used QuickPwn for Windows with 2.0.1 iPhone OS right after 2.0.2 was available to Update on iTunes.

    So, I took my MacBook, copied 2.0.1 bundles from PwnageTool, and added them on QuickPwn for Mac. Grab a 2.0.1 firmware image and QuickPwn'ed my 2.0.2 phone back with 2.0.1 files.

    Guess what? Signal raised a lot, enough to let me be able to connect back to Internet flawlessly -- just as it was last week.

    So, yes, 2.0.2 OS do reduces iPhone power transmition levels. I did not moved a bit my phone and the issues I was facing 5mins ago for the entire morning, just disappeared.

    I will try this with some other work mates which were complaining about signal power, and will let you know my findings.

    Also, if someone wanna give it a shot, feel free to let the world+dog to know about it.

    Hope it can be useful for you too.

    Just did this same on other 2 phones around. Signals raised from -88dB to -62dB, and -96dB to -68dB. 3 different carriers -- mine and other phone owners.

    Wierd.

    Atleast for both my 3G's, the reception has improved a helluva lot.

    I usually travel for about 45 mins in the train, each way from work and back, and I could never have a 45 minute long conversation.
    It was always getting cut almost every 5 minutes.
    The last week, ive talked the entire way, without dropping the call. (The signal does go down to 2-3 Bars, but the calls stays connected)

    2.0 / 2.0.1 vs. 2.0.2

    AT&T has said the reason calls were getting dropped is because iPhones were operating at a power level that was too high and many iPhones on a single tower would overload them in some cases. That being the case, it makes sense that a reduction in power level could result in fewer dropped calls.

    Mmmm... hate to break it to you, but you aren't downgrading the modem firmware. These observations are hard to explain.

    I agree with you. Technically, power level controls should be done by modem firmware, but some days ago an AT&T techie told world+dog they indeed lowered 3G signals on last 2.0.2 firmware. How they did that, if they didn't updated modem firmware?

    I do believe in hardcoded power settings inside iPhone Unix kernel (or under kext caches).

    Hey there guys 1st gen owner running 2.0.1. Yea these firmwares do modify the signal strength in some way. I noticed this when 1.1.2. At work I would get two bars of signal after that up 2.0.0 it was a dead zone. Then I went to 2.0.1 and my bars came back.

    Yeah, and with 2.0.2 you would probably get into dead zone again.

    Oh yeah, listening it non-stop over the previous 36h

    Kudoz to french store to antecipate me 9 days until my official downloads are ready

    And I have updated some more 1st gen iPhones from workmates these last 2 days, and on all of them I'm testing signal strenght after Pwning with 2.0.2 and after QuickPwning 2.0.2 with 2.0.1 files.

    ALL, I say ALL of them are having improved signal reception.

    No more complains about "omg how my [put your carrier name here] sucks that bad?"
