Although it's sad that the S3 may get the update later than the S2, but I'm also happy at the same time. My brother's S2 has been acting up after updating to 4.0.4 (the latest on T-Mo) I believe. I hope that 4.1 will fix the problems that have been occurring for him.
Come on Samsung/T-Mobile/Carriers. Get your work going. I'll be distracted with work, school, and obsession with computers for a while. But if 4.1 isn't out by the time the Fall semester is over, I might become like the cranky babies too(complaining about 4.1 release).
