Iphone 3GS keeps Restarting itself randomly

Thank you so much Saad!

THANK YOU SAAD!!! I was freaking out for the last couple days till I read you solution... you Rock mate!

I realised that the problem seems to occur when the SIM card is out of network, e.g. overseas SIM card. The problem recurs after I use Saad's solution but stops when I change the SIM card. The problem also seems to stop when there is no SIM card.

Saad, my iphone worked for a day and is "acting up" again... unfortunately! Any suggestions mate?

I believe the issue is related to battery overheating bc mine worked well but then the battery started to overheat and the phone self-reboots again.

The Self Diagnostic (General/ About/Diagnostics&Usage) states a "panic crash" report sent to Apple.

Seriously, APPLE should provide proper support and testing to prevent the issues from happening on the first place... it feels like they're loosing GRIP.

You call Customer Service and they either play dead or have no idea of what's going on... even though discussion sites are fired up with complaints!

In BRAZIL I was told by their OFFICIAL Authorized reps (ITAUTEC)

that the "mother-board" has to be replaed at a cost of U$D450,- when the issue is a SOFTWARE not HARDWARE problem!!!!

Hello, my brother had this same problem of the iPhone 3gs restarting cuz of the ios5. I tired enabling the 3G n dat but it only lasted for a few days them start rebooting itself again.... Try this method not sure how long it will last for but. Good so far.

General/reset.....Erase all data and settings.

On the iphone......Set up as a brand new iPhone.

Then log in with your apple i.d on your phone.

Once done, restore it from the pc and then sync ur backup with your apple I.d(if u hav 1) if u don't have back up saved it don't matter.

HOPE THIS HELPS YOU.

Because i know how frustrating it's been

hi rod\'s will it restart even if you are charging your phone?

hey guys, I'm from India,this is my first post here, I have just recently got an old iPhone 3gs 32 gb (black) from a friend since he upgraded to the iPhone 4s, anyway for the first week or so I used the phone like an iPod touch, sure there was a battery life problem and I did not blame it cause the phone is more than a year an a half old, so just day before I put my normal (not micro, not new) GSM SIM card from my old phone ..... this was at about 9:30 PM local Indian time.... and the following day, i.e., yesterday at about 12:00 NOON local Indian time the phone began rebooting itself.... it was freaking me out....my first instinct was that i should give it for repair, which I was gonna give anyway cause the body and the buttons of the phone were either broken or non existent or were about to fall off any second..... so anyway I did give it in ,.... and am supposed to get to know today evening, whether they were able to find the problem that caused the reboot issue.....

anyway between the time the phone started misbehaving and the time I gave it for servicing.... I had removed the SIM card from the phone and it was working just fine as an iPod touch.... so I came to a conclusion that the problem only occurs when the SIM is inside....maybe you should try taking the SIM out you will see that it works just fine....

I then read the posts here ... after reading saad's post I was relieved till i scrolled further and found out that it dint work .... so I Googled a little more and on another thread some1 mentioned a "dirty contacts list"..... so researched it, because when I began using it as a phone I copied the contacts from my old SIM card, and I came across this link about dirty/damaged SIM cards......

here it is: http://techtips.salon.com/problems-sim-cards-iphones-4466.html

maybe this could solve our problem, and after reading the post I took a look at my SIM, which I had removed from the iPhone and put back in the old phone, till i got the iPhone back, I saw that the SIM card is damaged really badly and has lots of scratches on it ......so when I get the phone back I'm going try it out with a new card, and see if the issue persists or does not exists, meanwhile you guys could also check the link and see your SIM cards and research further on the topic if you want to.......

I also searched further, "dirty contacts" could also refer to the battery contacts being dirty, literally, so I'm going to get that checked to....

thanx guys for reading

my phone keeps restarting, but i cannot turn off the 3g network, because my iphone has not been set up yet.

I followed sakran advice, and it's works, thanks a lot....
