Are you looking for a new Cell Phone? If you are mobile and rely on your contacts stored in your phone, why depend on the software from the phone. Upgrade to a Windows Mobile unit. With synchronizing contacts with Outlook, you will never have to worry about storing information with a sim card or on the phone itself, plus all contacts will have much more information available. Synch with 2 PCs and always have a back up of your valuable contacts.
Voice commands to dial numbers works like a charm.
