iphone making random calls

Same thing has been occurring on my 3GS, usu. after I finish a call. I'll put the phone down, or in my pocket, then I pick it up a few minutes later and it has called some number on my recent calls list, sometimes 4 or 5 times, figured it was me accidentally forgetting to lock the screen, but just happened a few minutes ago and all I had done, was set the phone down. The post above about the virus is really quite disturbing, I'm glad I checked this thread out. Thanks

Just to report the same problem, in my case, the phone seems to call when I hang up from a previous conversation. The iPhone calls random numbers in my address book, some of whom I don't even call but maybe text once in a while, it cannot be a user error. It has happened 3 times in a few months (that I noticed anyway), I wasn't happy when it decided to called my cousin's mobile in a foreign country, of course it went to her voicemail and lasted forever.
It happened again today, just after I called my boyfriend, I still had the phone in my hand when I saw the call being made on the screen to another friend I hadn't spoken to for 2 weeks. At first I thought it was an incoming call but realised it was the iPhone calling out by itself, and the call history confirmed this. Very annoying.

My wife's iPhone 4 with the latest iOS (4.1) just started doing this yesterday. It was on a stereo dock and was paired with a bluetooth headset, but she didn't press anything. It just made a call on its own. This is very disturbing since it was very late at night. I hope Apple can address this issue and offer a solution.

Same issue with iphone G3 running system 4.0. The last call was made to a number that has never been in my address book - I received a call from it just once, several weeks ago, that call wasn't even listed in the "recents". Not a chance that I could press any button by accident - the phone was locked.

Apple Support suggested "restoring as new" through iTunes and call again if the calls keep happen.

my phone seems to call the last person on my "recent" list.

could be embarrassing. yesterday a friend told me he had a voicemail from me and it was me putting talking to my son while we put the baby in the car. my friend said he wasn't paying attention to the message (couldn't tell who it was from) until his name came up and he heard me apologize to my son for being late b/c my phone had called my friend on its own and i didn't want to be rude and hang up on him. luckily, i think that is all i said.

but geez!

this is AWFUL!

My iPhone 3g with the latest 4.1 iOS began dialing out all by itself out of the blue last night - it was sitting on the desk in standby mode and had not been touched in a couple of hours, and the last sync / software update was 1-2 days earlier. It repeatedly called the last number in my recents (who happened to be a sensitive business contact), minutes or seconds apart. I did the 2-button reset, and called my own land line. It then started repeatedly calling that number all by itself, much more quickly seconds apart.

This was a very disturbing and serious problem. I called AT&T 611, spent 20 fruitless minutes with a rep who said he was new and connected me to a tech support line that answered it was off hours. I then drove 10 miles to the nearest AT&T store, where the rep was not sympathetic or concerned at all, and just demanded repeatedly if I had Applecare, and if not then it was my problem to replace the phone, and claimed I would get the same message from Apple. I then drove to the Apple store where it was nearly closing time and of course you had to have a Genius bar appointment, which couldn't be had until the following afternoon. Neither AT&T or Apple had heard of the problem before. The Apple Store greeter suggested restoring the phone. Both Apple & AT&T said it was unlikely to be due to the SIM card in any way. Both Apple and AT&T reps did the 2-button reset again, and the Apple rep tried turning off the TTY on a hunch - all to no avail.

The phone continued repeatedly & randomly call both the last 2 dialed numbers, anywhere from seconds to more than 1/2 hour apart. This finally stopped after I did the iOS restore. Total elapsed problem window, about 5 hours. It has been 20 hours now since the restore with no recurrence.

I dearly hope it never happens again. I've had the phone since it released in 2006, and NEVER had any problem like this - it's not only embarrassing but really very scary - this is my primary communications device.

There was no timely support available with either Apple or AT&T. The Apple rep was at least more polite, and admitted that even if I had bought Applecare as the AT&T asserted I should have, it would (a) not have gotten me official support help any sooner in this situation, and (b) since the phone is over 3 years old Applecare would have been expired anyway!

I wish there was official Apple recognition & guidance somewhere on the web for this kind of thing (is there?). The only suggestion/solution I know of - to restore the iOS on the phone & hope!

Has there been no reply to this issue? My phone has started dialing random number. The numbers are numbers I don't think I have ever called from my phone but they are in my 'contact list'. I would like to know what to do or how to fix it. It is rather annoying. I have had people call me and say why did you call me and not say anything. HELP ANYONE!

ps. I don't know what OS I have but I have a 3G phone that I have had for 11 months now.

I am having the same problem on the iPhone 4. I noticed this right after updating to the 4.2.1 OS. It seems to be automatically turning on "Voice Control" at random times and then dialing whatever it thinks you said. This is happening when I have the phone in my coat pocket or just laying on the table nearby.

My iphone 4 started doing that last night, it rang 4 people, and I didnt even it hear it ring them on my blue tooth I was in the middle of a dinner with friends and it was very embarrassing when 2 of the people rang me back the next day and told me bits of the conversation. The people are in my contacts but not favourites. This also happended to a friend who accidently rang me at 1am. This is not fun I cant trust the phone anymore
HELP

The problem is the home button for some reason decided to jam on activating voice control any random noise can cause it to think your asking it to dial a contact. Mine has been doing this for a few days it's embarracing hope apple sort this out

My iphone 4 just called my wife by itself while it was on the iHome. It did that quite a few times before. I had the same problem with my old iphone 3GS. So it must be a software issue. One most serious instant involving my iphone calling one of my prospective employers (I was on the short list for final decision) a few times late at night by itself while it was on my holster. I only caught it when I looked at the phone by chance. I was horrified that the call was on for a few minutes and I heard the annoyed prospective employer hollering on the other end. He never called me back despite my futile attempt to try to explain. Why Apple is not doing something to prevent this despite the numerous complaints simply escapes me! Any patch or fixes will be much appreciated - the Apple "genius" solution of deleting all my apps is not a viable solution!
