    Default [iPhone 3G] Poor Signal Reception

    Has anyone noticed a problem with reception with these units? In places where I usually get 4-5 bars with my previous phones, I only get 1-3 with the IPhone 3G.

    Well I wouldn't call it a problem, but my iPhone 3G certainly doesn't get the kind of reception that my AT&T Tilt recieved.

    I'm not too worried about the iPhone's reception. The Tilt's reception got better and better over time with firmware updates, and I'm sure the same will hold true for the iPhone.

    My only concern is the apparent issue that my iPhone experiences right after a restore or after being turned on. After a restore, my iPhone 3G said "no service" for over a minute before finally finding 5 bars. My house has perfect service, so this does worry me a bit. Do you have that issue as well kelkin? Anyone else that has seen this please chime in, I'm rather curious...

    I have had that too, no signal in a place which is usually 4 bars. A reboot of the phone fixed the problem. I've also had a few calls which sounded all.. well.. robotic, it sounded like I was listening to a corrupted mp3 or something.

    The same issue is occurring with my phone also, and I'm on Rogers in Canada. Probably related to the use of 3G, and I hope they can resolve it with firmware updates.

    Well I had this annoying problem since 1.1.4 on my first gen iPhone. It's unstable, but worse of all when I'm using wifi for a while (eg. using Safari, Youtube, or the AppStore now) the signal bar goes from 4-5 bars to NO SIGNAL, then after a while it came back. I've also noticed that if the iPhone is sitting on my desk I have from 3 to 1 bar, but if I dock it (so it's still on the desk) I suddenly get 5 bars.
    I'm doing I full system restore with firmware 2.0 right now and see what happens!

    I have to say I am somewhat disappointed with my 3G iPhone!

    I have noticed things due to my vacation circumstances that most people would never see with a single phone and be oblivious to its short-comings!

    I am currently vacationing in New York with my wife. I unlocked her iPhone Ver 1 several months ago but because she uses it daily and has no need for any of the newer features, I never got round to updating it. Her phone is software unlocked and is still running on 1.1.1

    I have a new 3G iPhone running 2.0 (5A347).

    Today we did the tourist thing (bus / boat tour). Admitidly I took more photo's on my phone than she did, but my phone ran out of battery (after being fully charged) by about 2pm today!
    I made no calls and took no calls all day, I missed one call and I had Wifi off!

    My wifes phone in contrast was still showing full capacity so I guess Apple were right about 3G in the first place!!

    Also, if the phone signal metering is anything to be believed (on both phones), the 3G is again very poor in comparison, I was showing barely any signal (synced to AT&T) in our hotel room whilst my wifes phone shows full signal. My wifes phone being unlocked was also quie nicely switching to other networks, theres was one point today when I noticed she was showing full signal on t-mobile, whilst I was barely getting anything again on AT&T still :-(

    Before anyone suggests I have a faulty phone, I have been dealing with iPhones since the launch last July and I don't believe there is anything wrong with the 3G unit I have, I just think its an unfortunate case of the old saying, "be careful what you wish for".

    Being from the UK, I was sad to see 3G not in the initial iPhone as our mobile networks are somewhat more advanced than North America (of-course its a lot easier to update a small island like ours than a huge place like the USA) but despite Apples claims about battery life (now they have bowed to pressure and released the 3G), they were right in the first place, it sucks :-)

    My experience has also been that the 3G network is responsible for both poor reception and poor battery life. I heard somewhere that 3G phones have to use a lot more power if they have poor reception, and this seems reasonable based on my iPhone's performance.

    If I turn off 3G, I get the same (or better) reception as my original iPhone and the same (or better) battery life. If I have 3G on at home or at work, I get one, maybe two bars of service (or no service at home) and I'm getting battery under 20% warnings by the end of the day. On 2.5G, I get 4-5 bars in either location and am only down to ~70% on the battery given the same usage. During the week, I tend to run 12 hours standby, 5 minutes call time, and 2 hours (WiFi) usage.

    I'm pretty much OK with all of this -- I don't need 3G at home or at work, that's what WiFi's for. Having 3G is great when I'm elsewhere, don't get me wrong. All I want is a one-tap toggle for 3G so I can switch it on only when needed. Why did Apple bury such an important switch in Settings>General>Network? With the jailbreak released, it probably won't be long, but I might have to start trying to code up something if someone else doesn't...
