Kynan lost his phone, and is regretting not knowing his IMEI. I realised I didn't have a readily accessible record of mine, so after a spot of Googling, determined that to get a Sony-Ericsson T610 to give up its IMEI, you enter *#06#. I could have sworn that Nokias used *#0000#, but Sarah's 5110 needed *#06# as well...
