sorry to answer that late (ok, it’s 05:42am ;-)) - i think it’s a connection problem - so, yes - open it again and check all the connections, search for broken parts in the area around the “do not remove” sticker

CLICK for a HUGEer version of the picture check both sides - the circuits around the golden spring are for the antenna - so if there is a problem - it might lead to those problems. surely - the antenny could also have a problem, but it’s not an antenna in the regular way - normally - it fails because of a bad connection
make sure the sim tray is flush with the top of the phone and that the aim card isn’t bent Update sorry sim card isn’t bent, I had this problem with a 3G it kept droping 3G signal then turning off then saying connect to I tunes then no service. I took out the sim card and the tray blew down the hole in the phone put sim back in and it has sorted my problem hope this helps..
you can get the 3G or 3Gs and 4G antenna signal coil here
hi my iphone 3g show no service …WHY PLEASE HELP ME
i have a quastion i have an iphone 3 but is giving me a hardtime with the signal always is going out of network and i dont know why i already checked the antenna and everything i d
I don’t have a iphone but have you tried disabling one of the bands and make it 3g only or 1x only?
iPhone 3G signal always drops out on my phone to the extent of me wanting to throw it at a brick wall!! It’s the worst signal ever, Iv heard that the iPhone 3G was fitted with a dodgy antenna which is shielded behind a metal cover which also helps destabilize local signal it makes me sick and very frustrated daily to know that apple released it in that condition and say that they’re not responsible for the signal… Technology, we can’t live it..but, we can’t live without it! Peace
Try shutting off your 3G connection (you find it under settings, general, network) and rebooting. If that solves it, then it’s a software problem. Dunno what to tell ya, cuz I have that problem too but if I kill the 3G, phone gives me no problems. CRAZY!!!
I’m on the ipad baseband, 06.15.00 an I lost both 3G and wifi. So far the only option I have found was replacing the baseband chip. But I can’t find it anywhere to buy. It’s a infeleon x-gold 608
i just replaced my 3gs and i have a new factory unlocked phone same problem keeps happening to me too i think it has to do with apples last update 5.1 i hade the problem with an unofficial unlocked phone but now the phone is a brand new replacement from apple so i don"t think it is your phone i think it has to do with an update or network problem. also i notes when when i use internet than the phone drops the signal.
I am 68 just bought iphone but I keep losing signal too, cannot deal with all the stuff put out there thinking of changing back to a basic mobile for peace of mind - what do you think people?
8/2/2012— update, do not try the method shown on youtube, where it asks to put your iphone in the oven, my iphone bricked. other than that, only software to help to atleast get the 3g back is the post below.
EASY SOLUTION!!!!! SO TYPE IN WHITED00R in google, and you’ll FIND OUT MORE ABOUT IT, DOWNLOAD IT FOR YOUR IPHONE 3G ON THE IPAD BASBAND, IF IT’S NOT GETTING 3G or its NOT GETTING SIGNAL AT ALL. WHITEDOOR: is pretty much a custom firmware for iPhone 3G and older devices that simulates the 5.0 software, although your iPhone will be running on 3.1.3, it will have all th latest features, and it’ll be fast. And of course, YOUR CONNECTION WILL POP BACK UP NOW IF YOUR WIFI IS NOT WORKING, THEN YOU NEED TO REFLOW THE PCB(YouTube it) THANKS AND GOD BLESS
and don’t forget to ACTIVATE your iPhone after a restore! Otherwise it tell you “no signal”… kept me busy for over 5 hours with mainboard and dock connector swapping… :(
If u having signal problem do following things 1 :try software mostly 80% having softwere problems in this case u can try to jail break them and them if same not working try to downgrade coz i ph3 and 3gs some time make troubles on 5.1.1 or up so max keep ur phone below 5.1.1 softwere virsion 2: check signal entina try to resold with heat gun and then clean with chemcial or patrol aslo clean golden plates with patrol better to clean all you bord Hope u will get signals..
