BlackBerry Pearl 8100

I can't find it anywhere...which is probably a bad sign. I had a few phones in the past that had the option of 2 lines on one phone/sim card. Does the pearl (or any other blackberry for that matter) have this capability??

I think it was some of the nextel motorola phones i remember having this fyi. If it matters I am with cingular but unlocked is an options if that helps.

Thanks for any information in advance!!
