It was reported yesterday that data connections of iPhones and iPads are throttled by three major US carriers through Apple. But this is not the situation. As AnandTech has issued a report today that claims about Apple is not throttling iPhone iPad data speeds with any of the carriers. As it was claimed yesterday that there are some specialized codes ruining on Apple iOS devices powered by AT&T, Sprint and Verizon whichi effect the network connection speed. But an investigation made by AnandTech has proven this statement wrong. Apple is actually not limiting any of its iOS data speeds for any carrier.
Apple has also issued a document on support forum that give details about the carrier settings process. Apple has explained in this document that how iOS carrier settings are being made. It includes APNs, MMS and other default app settings. All these files are not used in throttling iOS data speeds. There is also a lot more technical detail given in investigation for each data carrier company and proves that no such throttling issue is under taken by these and nor by Apple itself.
