Pretty much you do have to wait.  Not all nameservers update at the same 
time, so they should be update in 48 hours.

Before you do you next ones, a few days in advance, go in and change the 
times to about 1 hour.  Then a few days later, make you changes and they 
should be updating within an hour.
