Oh I used to own a Slide :) it’s a nice phone. (I’m rocking a BB Curve now, btw) When you go to add an email account to your Sidekick, it often asks about the protocol for the email (like Yahoo, Gmail, etc). Just select “Auto Detect”. Then fill out the rest of the information (like your email address and password) and don’t fiddle around with any of the settings. See if that works. I’ve used this method when I set up my college email on my Sidekick… Let me know how it turns out.
