Just found out that the 2.2 Upgrade stops wifi from obtaining IP address from even open/unsecured networks. Verizon guy tells me the only solution MAYBE a hard reset!!
This is getting worse,
Here is the list of things that I know of so far that 2.2 does to your phone:
1 - Deletes all pop3 e-mails
2 - Stops wifi from connecting to any network
3 - Runs unnecessary apps in the background & drains the battery much faster that before
