i'm sorry if that discussed before and right place to start this thread but i can't find anything.

n900 has trouble with the similar phone numbers like 10 years old mobile phones (and please don't say "it's not a phone!"). for example:

john doe 0552XXXXXXX
jane doe 0532XXXXXXX

everytime when jane calls it says john calling! i try to send an sms to john, typing the number manually, john gets it but my conversations screen says it's jane

thanks for further help and sorry for my bad english!
