4.2.1 - Apps & Folders slow/delay to reorganize pages - What's Up !?!?

Prior to my install of the 4.2.1 software, my apps started to jiggle almost right-away if I attempted to reorganize them by pressing on them for 1 sec. Now with 4.2.1 I press the icon for about 1 sec and they start to jiggle 5 sec later.

Also...when I attempt to lock them down by pressing the home button, there is again a delay 5 seconds or longer for to stop jiggling.

This all worked elegantly without delay in the previous 4.1 version.

As a side note, I am using a 32gb iphone and it's about 85% full (1/2 music, 1/2 apps). I have restored and reloaded the software, restarted the iphone, reset the phone, & I have reset the settings... No luck....

Is anyone else having this same problem ?

Also, I'd be open to suggestions for troubleshooting...
