Ugh I can't stand either to be perfectly honest. Nokias are strange, common and they are just weird and Motorola has a bitch of a smsing system (well at least the ones I've seen). So I don't go for either oh wait bah I'll go with Nokia. Their SMSing is slightly better. (I myself have a Sony Ericsson and before then an Alacatel).

Are you planning to buy a new cellphone OR are you happen with the one you have.
