No, both phones have to be powerd on,Have you tried turning on the old phone witout a memory card in it btw, sometimes the memory cards can cause the phone to reset.

thanks... But do you think it will work with one of the phones turned off?

Not with the phone off, the phone will have to be fully powered on for it to be able use bluetooth or usb cable, but there is a program on my 6630 that you can transfer data from one phone to another using the bluetooth, and the other phone doesnt need to have a sim in it, i'll try and find it for ya.

My 6600 just had a problem... It switches on but only for a few seconds. luckily, my insurance company just replaced it with a new one. My problem is the data that I had in my previous phone's memory. Is there any way to access them with the phone off? I'm only using bluetooth but thinking of buying a data cable. Will this do the trick?
