You can always clear the current defaults for a program by going into phone settings > applications. Find the app and push it's "Clear defaults" button. In this case, you could do this with the Email app.
Well I got the notifications shut off and it no longer receives the email in the stock app. However now when you open k-9 mail you have to click on the load 25 more deal before it receives them. any ideas???
I personally think its a problem with hotmail. When I was using the stock email alot of times I would have to refresh my phone and like 15 emails would come in when the phone turned back on. Would I be better off getting a new email service? What a good one to use with the droid
