    Default 3g Signal no 2g Signal PLEASE HELP!!!!
    Hi It's me agaian, still having a problem with my iphone
    following the jailbreak etc I only seem to get 3g signal and no 2g signal at all.
    anybody know of a solution or can point me in the right direction the closest I've got are the web sites below but unsure if it's a software or hardware problem (any other web pages greatly appriciated) Thanks guys.

    I feel its a bit like the x-files for the Iphone; "The Truth Is Out There" somewhere at least I hope so!

    Sounds like a software issue not a hardware issue.
    Was it doing this before the jailbreak?

    I actually had a phone that it was a hardware issue causing this exact symptom. Not saying it isnt software but it could be hardware.

    Could be depends on if this was happening before jailbreak
    If it wasnt or you not sure try to restore first and see if that fixes if not then we can crack the phone open

    I've tried a restore and all the usual stuff but nothing on the way home I discovered I can get signal on 2g but is very patchy and I have to be stood practiculy on the telephone mast to get signal, I'm pretty certain it's the arial in the phone from the web pages It dosn't look very easy to change (they talk about soldering a piece of wire instead of the resister that attracts the signal, but I just needed some advice or even a step by step tutorial on how to do this,

    thanks

    Why do you not just buy a whole new piece instead of trying to solder it and making a mikey mouse fix.

    ah theres a problem there dude, the piece you describe is the wifi antenna but there is two (I want the GSM Antenna)

    Where is cellular antenna connector - iPhone 3G - iFixit

    How I recovered my iPhone's lost GSM signal!

    I am in fact one step ahead of you my friend, as I have bought that exact piece you describe 2 days ago and am waiting for it to arrive, but having looked into it more closly I don't think it will improve what I want it to improve (as you say about soldering being a milky fix I agree. I have no intention of doing any soldering as I was terible at that side in electronics at school) I think I'm looking for a pacific resister but I think it's a trip to an Apple store or an electronics genius and pay whatever the cost is to get it fixed.
    what do you think dude? Thanks

    Rich

    by the way these pictures are for a 3g Im on a 3gs (i could be wrong but i'm flailing blindly in the dark on this one now)

    Posted later; (sorry I meant a mickey mouse fix)
