7100g.....I think it's any day now. For some reason, I thought someone told me tomorrow for the 7100g (05-JAN-2005), but don't quote me on that!
As for VeriChat...I'm using it on my 7290 now. I do have BES/MDS and it works great!
I think Cingular released 4.0 (for all EXCEPT 7290) today. See http://www.blackberryforums.com/viewtopic.php?t=1995
I'm told to expect 4.0 for 7290 from Cingular in late Jan / early Feb.
