My vote goes to pusheffect. The only downside I've experienced with it so far is when someone sends you an email with an attachment. When that email gets forwarded to your sprint sms address (xxxyyyzzzz@messaging.sprintpcs.com), it gets bounced because the sms system cant handle attachments - so basically it never gets pushed. If gmail had the option to strip attachments from messages before forwarding, this wouldn't be a problem. What I did was set poutlook to send/receive every hour or so incase someone sent me an email with an attachment...unless someone knows of a fix for this?

Emails without attachments are NO PROBLEM - sometimes I get the notification on my phone BEFORE its available through the gmail web interface! Plus its a process that doesnt kill battery life. It only gets triggered to send/receive when you receive the forwarded sms.

EDIT - forgot to mention how I sync my contacts and calendars.
I use nuevasync for it. First - I backed everything up of course. Since this was going to be the first time I synced up with my google contacts, I knew that there were going to be duplicates and whatnot. Boy was I right. Nevertheless, I wanted to make it work, so I just rolled up my sleeves, activesynced it back to my computer and did all the merging, editting, and deleting there. Once done - I activesynced back to my Diamond. Everything seems to be working fine now - google contacts got rid of their erroneousness too once I was done. Hope this helps!
