Matthew Panzarino of The Next Web reports that Sprint knows about, and is working on, the slow data speeds frustrating many iPhone 4S
Now it seems that an internal email has been sent to Sprint representatives, informing them that Apple and Sprint are working together on a “confirmed nationwide issue” dealing with the slow data rates many users are experiencing. There was no information about what the cause of the issues are or what the expected resolution date might be.
Since the CDMA iPhone 4S is limited to EV-DO rev A speeds, they're going to potentially be much slower than an HSPA 14.4 AT&T iPhone 4S, but they should be equal to the similarly networked Verizon iPhone 4S.
Check out the link below for the details and, if you're on Sprint, let us know how your data is performing.
