iphone 3GS - no sound without headphones

Andy Your a genius! 2 minutes work and I'm up and running again.

I have the same problem.

My iPhone 3GS sounds are not working on Messages, facebook, alarm, reminder.

But it works when some one call me.

I am not using head phones,

Tell me what is the problem?

I reset my iPhone, erase all content and data, reactivated it.

But still same problem

I am using iOS 6.1.3.

Regards

On my 3GS the problem was dust / debris in the docking connector or headphone jack. I think the debris caused the phone to think it was docked (and thus sound should not go through the internal speaker).

I used a can of compressed air to blow dust out of the connectors and sound starting working again.

Can you tell me which Game it was?

It seems the same issue with me but I dont remember the game. My niece played earlier night and my brother deleted the game. Both of them dont know which game it was.

I would like to install the game which you did then try to mute & unmute.

Thanks.

I am not 100% sure and now my daughter has her own iphone and she is away on vacation and I deleted her games but if memory serves me right it was Stardom!!!

Or one of that category of girly games, hope this helps

Thanks this sorted the problem for me. I dropped my phone in a mug of tea (yep i did) and the cotton buds worked. Thought I was going to have to get an Iphone 5

I had the same problem for a second time today. I took the SIM card out for about 10 seconds and when I put it back in sound returned. I think I did the same thing last time. I did have sound through the earbuds, bluetooth and with speaker on. This seems to reset normal sound.
