if its slow right out of reboot, then whatever new software you've just recently installed is causing it.

Today items can cause it, any apps that run in the background can cause it. Making some changes to the registry can cause it.

Try undoing whatever you've done recently. If that's no help, and you're prepared to reload data and apps from scratch, a hard reset (NOTE YOU WILL LOSE ALL INTERNAL DATA/CONTACTS/CALENDAR/SETTINGS/INSTALLED APPS yada yada... have a backup... sync... etc...) will get you back to that "out of the box new phone smell" state - from there you can start loading it back up with crud until it falls over. Then you'll know what's doing it.

In very rare cases, oddball situations like very marginal signal, and even hardware issues can cause the molasseses mode to kick in. If you just can't get rid of it, its time for a trip to the carrier to get a replacement.

Good luck!
