I use the Gmail application.
I actually can't get BIS configured. I used it with my last BlackBerry, and it was awesome, but I haven't been able to create a new account with my Curve. The Web site (https://bis.na.blackberry.com/html?brand=vzw
) tells me I must access that HTML on my phone to register a new account. When I try that, my BlackBerry tells me it cannot load that HTML.
The e-mail hasn't really been an issue, though. Nor has the data, as I have an unlimited plan.
My problem here is that leaving AIM logged in on my BlackBerry seems to be draining my battery life.
I used to communicate with someone regularly on BlackBerry IM, but that user now has an iPhone, so we're trying to use AIM instead. I want to find a way to stay available on AIM that doesn't kill my battery.
