When HTC unveiled the One X, it also announced that all One series owners are going to get 25GB of free space on Dropbox for Twitter. Samsung up’d HTC when it announced that all Galaxy S III owners will be getting 50GB of free space on Dropbox for two years.
Sadly, it looks like this offer from Samsung won’t be valid for the U.S variants of the Galaxy S III. Quite a few people in the United States who have already managed to get their hands on the Galaxy S III in the United States complained about not getting the free storage space after signing up on the Dropbox forums. This is when a Dropbox forum moderator chimed in and announced that some of the U.S carriers have opted out of this promotional offer.
For some unknown reason, Verizon and AT&T have both opted-out of this promotion offer with their variant of the Galaxy S III. It is still not confirmed whether Sprint or T-Mobile have also opted-out of this promotional offer or not. I am not really sure as to why AT&T and Verizon opted-out of this offer, when the promotional offer is still valid for the HTC One X in the United States.
