How To Inter-Transfer Contacts nd Messages on Different phone BrandsAny1's got a very good Intelligent idea of how best to achieve such ??

Been trying to transfer my whole Contact nd Messages from one Brand of Phone to another, say From
Nokia N95 to Sony ericsson K80i Yes, I knw There's is the Bluetooth option, but its seems way too
tedious nd prone to
lotta' errors too!
Sure, you can easily transfer from a Nokia Phone to another, . . in a giffi using the
Nokia PC Suite! 
Any better way to
Inter-Transfer?
