I think that phone of yours needs re-programming.. Refrain from turning it on again once it shut itself down. Better have it checked by a trained technician. :)

the truth is that you can unlock the phone for free,but you can unlock all phone for free. The payment sites are very very cheap you could try it out and see.

There is a free site you can try out first but it is for soft

unlock not hard unlock.You can use this link for the soft unlock,

then trying out that with this site (www.unlocktotalk.com/UnlockCodeInstructions.htm),

you will now try out the hard unlock with the site below
Note:hard unlock is not free,You will be charged to get your unlock code.

The only way by which you can get the unlock code for free is by calling your service provider
and requesting for your unlock code.
If you service provider refuses to give it to you, then there is no other place where you can
get a free unlock code.

Visit the link below if you are interested in buying the unlock code:


Good luck.

Hey thanks for using fixya
Actually by default there is no any trick to listen fm without earphone. If u want to listen not from he headphone, then its better that just attached the headphone with Handset, Now go in options of Radio, There is option as "loudspeaker" now you can listen fm from loudspeaker.

I hope it 'll be helpful for you.
Kindly keep thumbs up for rating.
