Hello sir, i have HTC 3400i mobile phone i want

Thanks for this great app link

Connect the HTC Desire to your PC via the USB cable, so that you can get to the .VCF card that was just created. Log into your gmail account and click on the contacts menu choice on the left side. Choose the "Import" menu choice at the top right of the contacts list now and select the .VCF and press Import. This will load all those contacts into your Contact list in Gmail and the next time you reset your phone and you resync with Google all your contacts will be then available again on your HTC Desire.

Other solution try Vibosoft Android Mobile Manager:
