Ok, firing up my wifes evo, but her email server is secure, unlike mine. I and she will hate having to unlock the screen everytime. I found an app on the Pre to disable it, but can't can't find one on the EVO.
My company's security enforcement with EAS means I can't use a pattern unlock and the default text/PIN unlock screen is so ugly, I couldn't stand to look at it each time.
I actually prefer a pin unlock or a pattern unlock, because I don't want my friends to randomly start searching my phone (or spouses??? ;-) ). However, I just HAD to get LockPicker to remove the ugliness. It works well with the EAS enforced security policies.
