I have iPhone 3g can I update it to 3.2 will it work good .
Had the same prob after update phone was dead. I went to at&t, they changed my sim card now all is GREAT. Give a try its free.
hello
i have 3gs iphone which i recently update my software to 4.1 but no i dont get any signal it was working perfectly before now what shall i do
My iphone is useless since the new update. it was great before now no signal. Missing calls etc, Come on apple 🙁 How can i undo the update? and get back on mobile. grr!
Updated my software, terrible signal since. Now I average 1 bar in my house, and maybe 2-3 outside. Unbelieveable.
Same problem after the update. All I get is “no signal” or “searching” which drains my battery. If I do get a signal it is 1 bar, while the iphone my friend is using next to me is 5 bars and no problems. This is ridiculous. Called AT&T, they said it was a software problem that I have to take up with apple?!?!?
I’ve just updated from 3.2 to 4.0.2. I’m now receiving very little signal and very often its saying no service. Any ideas on how to restore 3.2 without sshh files.
Thanks
Before the update was getting full bars all the time, I noticed my signals are now always at 1. But when I make a phone call, bars raise to 5! When the call is over, bars goes back to 1. I sometimes don’t get the wifi signal when there’s wifi.
Please fix! Thanks!
I couldn’t make the iPhone 3G work so I bought a iPhone 4 a couple of days ago and sent the old 3G to service. Luckily we have 2 years of warranty in Norway 🙂
first month of having the iphone 4 software on it was fine, no problems, but recently i cant send txts, constantly have no signal, took a hour today to get signal in my room, was trying to make a phone call, with two bars of signal, and it still wasnt working.
I don’t think it is the updates causing the dropped called and no signal bars I think it’s the network cause I haunt up graded and same thing is yapping to me
Same problem! Never had so many dropped calls until I did the “updgrade”. Is there a fix?
Fredrik here you go…

After updating my iPhone 3G to iOS 4.0.1 it tends too lose the signal all the time and I am left with “No Service”. It is really annoying because I cant make phonecalls or send/recive messages. I cant figure how to sucsessfully downgrade to iOS4.0 🙁 Any ID?
i have a 3gs running on 4.0.1 and i think its great no problems with signal bars at all!!!
really happy with the upgrade.
after the update 4.0.1 my iphone 3gs have poor signal in places where the signal was very good. I´ve also difficulties to make and receive calls all the time. The upgrade is BAD. It does not work at all. Guys do someting to correct this NOW. Is really stupid to release an update to worsen things !!!
i did the update 4.0.1 on my 3gs and i have poor signal, one bar at my house i used to have 5 bars, and i get dropped calls all the time, i thought atnt was problem so it turns out everyone is having same problem with this stupid update… apple do something about this, its bull shit. my friend has a 3g phone with old update gets full bars at my house, so he did the update 4.0.1 to see what happens and hes phone got 1 bar he lost reception. so thats proof that the new update is BAD!!!!
The 4.0.1 for the iPhone 3G is terrible. I wish I had never done it and tell everyone not to do it. I have lost most of carrier signal, which is AT&T. My Microsoft Outlook will not update most of the time without turning the phone on and off numerous times, and now that is not even working. iPhone is terrible slow, just horrible. You guys need to do something.
ever since this new update i have had no service most of the time and signal i did get is about 1 bar please help dudes
Used to have full signal and 3G signal at home, since 4.0.1 I struggle to get a 3G signal at home
Before iOS 4.0.1 on my 3G, the carrier signal strength was full, now it is missing at least one bar all the times.
experiencing lots of dropped calls and poor signal quality after the update to 4.0.1. have ruled out any hardware problems.
