Not sure if this has been reported yet, but I upgraded to 2.3.6 yesterday on my Captivate and have some huge issues now: 1. The screen PIN lock does not work 90% of the time. My employer requires me to have a PIN set to unlock my phone in order to receive emails from our Microsoft Exchange Server. This worked fine with 2.2, but since upgrading it no longer works. I went to AT&T...no help. They suggested that I buy a new phone with 2.2. I called Samsung...no help. They suggested that I do a factory reset! 2. You lose the ability to manage your data connection as they have removed the feature that allows you to enable and disable the 3G connection. Hope this is some value to you all.
