Pardon me if this has been covered before, but I didn't see it on a couple of quick searches...

Can you check your data usage on the Sprint website? I have a Treo 650, which has the DUN hack installed. I also have a Dell x50v, and an Apple Powerbook, which I have been able to get working with the Treo. On the rare occassion I will use the Treo as a modem with the other two device; it usually occurs when I need to use my Powerbook in a place where there is no other internet access except Sprint PCS.

So is there somewhere on the Sprint website that I can check for my current monthly data usage? I am just a bit paranoid about getting hosed with "overuse" charges if I inadvertently overdo it by going over a reasonable amount of data use.
