9210 Ebay trouble !!!! PLZ HELP

Hi all,

Im a newbie to this site.

Just recently bought a 9210 off ebay, GREAT phone but over the last couple of days i have been having problems with sending texts.

some one called me today and couldnt get through, so i called the network to find out that my new toy had been blacklisted !!!!

short of going to the guy i bought it from and offering him large quantities of pain and my money back. can i get the imei number changed ? i have a fbus cable and netmonitor activated but am having no luck.

all responses will be greatly appreciated, im in the UK and dont mind having to send the phone away to be done if need be

Thanks again
