It's confirmed. I had problems upgrading to ICS from Gingerbread, but T-Mobile and Samsung solved the problems. But before I did the upgrade I read
the ICS review at PCMag.com, a glowing one, but a few reservations, one, no flash, two, ICS needs more resources (I figure 2 gigs RAM, minimum of 1 gig), three, slower on some devices, and four, some apps you have may not work on ICS. I'll wait. I like my Samsung Galaxy S Blaze. I'll wait until cI can afford the S III.
