Zach from Symbian in Motion just came back from the Flagship Store in NYC and posted on Jaiku that the N95 with 3G frequencies, larger battry and more RAM will be available next week. This falls in line perfectly with the Nokia Party that is supposed to be happening in LA next week.
The official specs can be found on Forum Nokia.
