Unrooted Incredible: how do I get back to 2.2?

[jdshort2010]

Hello everyone. I'm new to the site so if I post something that has already been answered somewhere else, I apologize. I'll make this short and sweet --- I recently tried to root my incredible and something went wrong and I was unable to fully access Superuser Permissions. So, I decided to just undo the mess I created and started the unrooting process. Everything went well, however, before I rooted I was running 2.2 and now I'm in 2.1. Will an OTA update come? If so, how long? Its been 2 days since I unrooted. Should I wait longer? Any help would be appreciated.
