Sprint initially denied having any problems, but TheNextWeb has published a report suggesting that there indeed is a problem with the data speeds on Sprint`s network.
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.
If the issue is nationwide then it is likely an issue with either the device itself or its baseband firmware. Hopefully Apple and Sprint can resolve this soon and Sprint owners can begin browsing on their iPhones at full speed.
