ever since updating to the latest iphone software and recent carrier update, virtually EVERY call is being dropped after a few minutes. I went to AT&T and they replaced the sim card which did nothing. I live in the middle of a big city, i do not understand whats going on. is anyone having this problem too???

iphone 3g, iPhone OS 3.1.2

    No such problem here.

    Have you tried restoring your iPhone with iTunes - first from your iPhone's backup and if no change, as a new iPhone or not from your iPhone's backup?

    I get frequent drops, but I can not say they all get dropped. One thing I have noticed is that when I do get dropped, my phone is in the process of swapping from 3g to edge, or just switching from anything to anything else. My phone used to never drop calls, and it did not start until I loaded 3.0.. 3.1.2 has been no better, or worse for me.

    This is a constant problem in and around DC. A simple 2-minute phone call now takes up to 15 minutes with all the callbacks because the call is dropped repeatedly. I also get this HORRIBLE screeching sound (brother calls it "the aliens are coming" noise) that both the person I called and I hear and usually precedes the disconnection. While I love the iPhone's potential, and I've been an Apple-person since the early 80s, I long for my LG on Verizon. I'd love to know whether it's the phone or the network. And I'd REALLY love to know who's going to own up and fix it.

    A rep at the AT&T store said he'd never heard of the dropped call problem. Somehow I don't believe it.

    I am having the same issue! When i talk on the phone for a long period of time I start hearing that "alien" noise and then it drops shortly after. It gets really annoying and creeps me out sometimes. Does ANYONE know how to fix this??

    Same problem here! iPhone 3G v3.1.2 - 05.11.07
    Dropped calls on every call! Today I could not speak on the phone more than 3 minutes without it being disconnected. I'm heading to apple store tomorrow to get a diagnostics. I used have dropped calls before but not on every call that has been happening lately. I am hoping the phone is bad, if not .. you know where I'm heading.

    I've also been having this problem. 98 to 99% of my calls are dropped within 5 minutes. Full bars and the like. In Columbus, Ohio. Called ATT and they rebuilt my account from their end (??)... didn't help. I've reset/restored from my end. This has only been happening since the last software update.

    Can't remember exactly when it started, but I've been using an iPhone since release, and it's only been in the last few months that this has been an issue. At this point, all I can do I guess is cross my fingers that the next update fixes the issue, and that right quick. It's ultimately frustrating to be at the mercy of an obvious glitch like this. /fist shaking

    Here's hoping

    If no change after an iPhone reset and after restoring your iPhone with iTunes from your iPhone's backup and/or restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup, you can try getting a new SIM card for your iPhone from a local AT&T corporate store. There should be no charge for this.

    If no change with a new SIM card, you can call AppleCare or make an appointment at an Apple store. Your iPhone may have hardware problem.

    Allan, I appreciate the quick reply . I may indeed find my way to the apple store to pick their brains about it. I suppose the reason I haven't done this yet is that I've read a number of posts on these boards, of people describing exactly the same issue. I mean exactly. I suppose there could be a hardware issue that cropped up in my iPhone, after the last software update, and along with many others, but that just seems unlikely.

    I did read a post somewhere (not on these boards, and unfortunately I can't remember where) that described in a very technical way, a possible reason. It had something to do with the phone's communication with the the cell towers. It boiled down, as far as I could understand, to the phone asking the tower for more signal strength than it really needed, and as a result, the tower would eventually drop the call as kind of a safety cutoff. Perhaps analogous to the compressors and gates that radio towers use to protect their broadcast amplifiers. Again, this post was very technical in nature, and although I'm fairly proficient in that language, the particulars as it pertained to the nuts and bolts of cell transmission were a bit over my head.

    If something like that were the cause, then I could see a particular software update for the iPhone, along with the particular cell network in Columbus, Ohio having some weird incompatibility. I don't know.

    Again, thanks for the reply.

    Any call over 4 minutes gets dropped. Apple provided me with new 3GS with an average of 70% dropped call rate, basically told by Apple that it's At&t's fault. Since receiving my new phone still having constant dropped calls. Went to the At&t store last night and they told me that they are not having any complaints of issues with dropped calls. They gave me a new sim card last night and still had 3 dropped calls today.
    Everyone in the office who has iphones is also having many issues with dropped calls. I like the phone, just can't use it as a phone. Very, Very frustrating. Feel like I am back with Sprint! Someone please fix the problems!!!

    quick update to my earlier post:
    After apple store recommendation, I went to AT&T store and they got my SIM card changed and It actually improved things quite a bit. I used have 80% dropped calls , I could not speak more than 3-4 minutes, now I have much less dropped calls may be 1 in 5 calls gets dropped and I can stand that. This is in New York City. I hope this helps people having the same problem.

    I live in the worst part of SF for AT&T coverage and their recommendation to stop the dropped calls and low signal fluctuations was to turn off 3G. This works for me because I have WiFi at home and that's faster than 3G anyway. Call clarity has been better and dropped calls are virtually gone. Not the best solution maybe but it works. I just have to remind myself to turn 3G on when I'm in a different part of the city. FWIW

    I too live in Columbus. I have had a 16Gb 3G for 18 months and am pursuing buying a Blackberry despite my allegiance to apple products. I believe I own every consumer apple hardware product currently sold. That being said, My 70% dropped call rate is unacceptable for business use.

    I took my 3G into the Easton Apple store during a Genius appointment and learned that 68% of my calls in the past week had failed. They issued me a new phone under my apple care protection. I've been using the replacement 3G for 30 days now and have not notice any improvement. I can't imagine all of our SIM cards are all of a sudden bad, so I am ditching the iPhone as soon as I can get AT&T to back a discounted purchase of a new Blackberry Bold9700.

    All I can say is ... UNACCEPTABLE Apple and AT&T. You just lost one of your biggest fans.

    Turning off AT&T's 3G network seems to help with my problem of dropped WiFi calls on my iPhone 3G. I agree that this is not an elegant solution because I have to remember to turn the 3G network back on when leaving our home WiFi signal, but so far it seems to have helped with voice clarity and dropped calls.
