I don't have either of those phones, but I would have thought you could go into the phone book and select "copy to SIM" on the first phone, and then transfer it to the new phone and select "copy from SIM".
As spacechimp said - that's how I did it from a Motorola L6 to a Samsung 'Cookie' (daft name but very nice touch phone). In fact, I'm not sure if I had to 'copy to Sim' even, just inserted the Sim in the new phone and then copied from Sim (If you keep that Sim in though, I think you get two copies of each contact in the phone). Were you wanting to us a new Sim?
Thank you both for your helpful answers.
Wideboy : I want to keep the same SIM also I have lot of contacts and it only appears to copy about 20 then gives up!?
Any suggestions?
