I just talked to US Cellular Tech Support and was told the Acclaim would NOT be getting the 2.2 update period! I was really pissed as the sales guy who sold me this phone said it would be updated "soon". That was over a month ago.
I emailed Samsung and they refused to confirm if/when this phone would be updated. In my book, if you aren't even willing to say IF you will update, that pretty much means NO. I replied and told then I would not be buying any more Samsung products if this were the case. I would encourage everyone here to express the same sentiment.
