Neither the phone nor the OS are obsolete as they're both in use and capable of easily matching any phone released today as far as functionality. Obsolete would be a phone that cannot run current applications due to hardware or software issues or whose functionality is far inferior (like having a VGA camera or similar), neither of which is the case here.
