I'v been tyring to figure out how I can get the same mail account on 2 phones. One is a Sprint domestic only phone and the other is a TMO international phone.

I could set up an exchange account to forward to another exchange account and have that account on the 2nd BB.

Any one have any thoughts or better way of doing this? Is there some secret hack to have 2 BB Pins going to the same mail account?

If all you need is email (not wireless PIM) on both, then set up one BB via BES, and the other BB via BIS.
The BES device will give you wireless PIM sync, but the BIS device will only give you wireless email delivery.
