This has been one of the frustrations I have had with the N900.

I live in the UK but most of my family are in Nigeria. When they come over to the UK they have a UK number. On my N95 I would label that UK number UK Mobile. If they have only one mobile in Nigeria I would label it Nigeria Mobile.

It is very common for people in Nigeria to have like 4 mobiles (one for each mobile phone operator). There is likely to be one it is easiest to reach a person on and I used to label that Mobile Main. For other numbers I could label it with the network name. If they have a blackberry I would label the blackberry number Blackberry. Now on N900 it is all a mess and I cannot really identify which numbers are which.
