I paid a visit to my local Verizon store last night. I asked one of the salespeople if they knew whether the Ally was going to be upgraded to 2.2.
He siad he didn't think so, but before he could finish his answer, another rep who had overheard my question jumped in and said that the Ally was definitely getting 2.2, but they had to do a couple of minor updates prior to the 2.2 upgrade. The rep also said that LG wanted to boost sales of their newer phones before giving the update to the Ally.
Here's hoping they are correct.
