Check Email Timing

[Runbigmama]

Now I know this will sound a little absurd to some of you nuts that have to have your battery last for days, but is there any way currently to have your email checked every minute? the smallest I see is 5 min.

The reason why is b/c i don't want to pay the extra $20 a month for unlimited texting, and with how much my girlfriend texts me I would need it. What I have now is her just texting back and forth with me through my email, which works great, just a little slow.

And then on top of that, not to be burdensome, disconnect from the internet after it has sent and recieved?

Im sure the latter cant be done, but I know a lot of you are phone geniuses, and where there's a will there's a way, right?

Thanks in advance for any of your help guys.
