I've heard that calling Fido and asking for "number only" caller ID instead of "name and number" fixes it. I'll try that tomorrow.
I had a problem with my no-contract Lumia 710 on Rogers where people from Telus/Bell would come up as "UNKNOWN" on my phone. I looked the issue up, and it turns out, this isn't new between Rogers and WP devices.
What I did to solve this issue was basically...call Rogers, tell them to remove my combined value pack (has caller ID, name display, voicemail, etc), and then replace it with *just* caller ID, voicemail, etc, but *no* name display. Issue resolved.
