Sorry for going off-topic here a bit.
@ Whatleymeister : If you have an unbranded Desire S, you should have 2.3.5 already. If yours is branded however, you may need to wait.
Normally HTC releases these updates first, and then the individual carriers modify them for their own customers.
Go to : Settings -> About Phone -> Software updates -> Check now
If your phone is unbranded, you should get a message about the update.
Right, back on topic (hopefully)
