Blackberry as a Modem

Let me start out saying, this isn't for using a blackberry as a modem just to get on the internet with a laptop. I'm actually wondering if you could use the blackberry as a real modem to dial into another modem, kind of like using it as a dial up connection?

From what I understand, no. The BlackBerry isn't a "true" modem. It doesn't make an analogue connection the way a POTS modem does.
I have heard rumors that the Storm can, but I've never gotten that confirmed.

Feel free to try though.
