Limited data plan

[ksg]

I have a co-worker who has an Apache on Verizon Wireless. However, he doesn't have a data plan. If he uses any data, it comes out of his wireless minutes.

So, if he uses data during off-peak (nights/weekends) time it is free.. however, during "peak time" he is using his precious minutes.

Now, here is the question: When using Pocket outlook there is options to have it check for e-mail every 1 minute, 5 minutes, 15 minutes, 1 hr, 2 hr, once a day, manually, etc. Is there a way to schedule it to use his data plan during off-peak but to only go manual during peak times? Obviously this would be a third party program, but does anyone know of such a beast?

Thanks in advance.
