It looks like Sprint subscribers who were lucky enough to get a 4S are not happy with the download speeds they are currently getting. Because of the complaints an internal memo has been sent to Sprint reps letting them know the issue is being worked on with Apple. Not surprisingly the issue is attributed to the fact that iPhone users download a lot of data.
From the “Everything is fine” department at Sprint:
“Overall, iPhone performance on the Sprint network is consistent with our expectations and the rest of our high-end portfolio. However, we do see opportunities to optimize performance, specifically in high network capacity areas,”.
Sprint is feeling the same pain AT&T did in New York City and San Francisco, only theirs seems to be nationwide.
