wrong date sms from SIM -> phone

[möp2]

hey guys,

i have a problem with my nokia e61. i wanted to keep some sms from my old phone so i copied them on my SIM card to import the old sms on my e61.
works quite fine so far, only problem is if i check message details it shows my the time and date when i copied the message on my e61 but not the date when i actually received the sms on my old phone. i did not have this problem when i did the same with my sony ericsson p800. any ideas how i can convince my phone to shown the original date? are there tools to edit or something?!

thanks for your help!
