I'm having a similar issue. When asked to enter the password, I misunderstood the question and entered my password for the server, which is a complicated mix of all kinds of numbers, symbols, etc; requires me to go back and forth between letter and number screen several times, really a pain to enter! So 2 questions:
1) how do I get back and change the password to something more simple?
2) is there an app that lets me choose when to password lock the phone? Honestly, I like having the password ability in some situations, as someone could really wreak havoc on my professional life w/ access to my Outlook and other programs. But when I'm at home or at my desk w/ the phone next to me, I don't need the lock protection.
