A big problem about iPhone 3G speaker

[catflower]

Need your help!
Excuse me. I live in Taiwan and my english is poor.
My phone is "iPhone 3G 16GB, unlock, no jailbreak, firmware 2.2.1".
Someday I used the speaker, my iphone broken line.
I have to restart my iphone to use it again.
Someone knows what's happen.
Someone can help me, please?

Thank you so much.

Ok calm down,

What do you mean by 'my iphone broke line'?
And what happened after you restarted?

Also what do you mean by 'unlock, no jailbreak'? how is it unlocked without jailbreak, factory unlock from the store?. (unlock is so you can use any cellular network)

Thanks.
I am sorry for my poor english.
I can use any cellular SIM in my iPhone.
"Break line" means when I use speaker to converse, I miss the cellular network(no signal).
I have to restart my iPhone, then it can receive the cellular signal again.
Please help me.

Thanks.

By speaker do you mean:

-the one in the iphone
-a outside speaker that you connect through the little hole on top (headphone jack)
-a outside speaker that you connect into the big hole on the bottom
-a headphone/earbuds, (small speakers that go in your ears)

And by converse do you mean talk? In the phone app on speaker phone (loud) or normal (up to ear/head)

Or do you mean something else like

-music
-video
-apps
-ect

Thank you.
"Speaker": I mean when someone call me, I press the screen "Speaker" to sound loudly.
That is, "converse" means talk with someone by my iPhone. When I press "speaker", my iPhone miss the cellular network(no signal).
You say "In the phone app on speaker phone (loud)" is right. That's my means.

I am so sorry for wasting your time. Thanks again.

Ni hao catflower,

That might be a problem caused by the sim card adapter. I have read where when using certain sim card adapters some functionality of the phone will not work properly.

If you can I would try using a different SIM card adapter.

Thanks.
I will try to use another SIM card.

I use another SIM card yesterday.
But my iPhone "speaker" don't work yet.
Do anyone have the same experience?
Or who can help me?

Anyway, Thanks a lot.
