Put on the tinfoil hat, developer claims Apple is throttling iPhone data speeds on three major US networks.

Are carriers throttling iPhone data speeds?

If your iPhone’s data speeds don’t seem to be operating as advertised, it might not be your local network, and you might not be crazy. That’s the word from Joseph Brown, one of the developers behind iTweakiOS. According to his research, Apple is throttling HSPA+ and LTE data speeds in an effort to reduce overall network strain due to theĀ prevalenceĀ of the iPhone.

Brown says Verizon, AT&T and Sprint are all guilty, with the only carrier not exhibiting such data caps being T-Mobile, the most recent to pick up the iPhone. In the case of AT&T’s iPhone 5, the phone appears capped at 14.4Mbps when it is fully capable of up to 21.1Mbps.

It isn’t exactly clear who the responsible party is, whether it be Apple or the carriers. iTweakiOS is providing a number of hacks to unlock iPhone data speeds regardless. But I’ll put the question to you: have you noticed a drop in iPhone data speeds or general laggy cellular data performance? Let us know!

    I simply can’t imagine what throttled Sprint data would be like. OMG.

      HA! True that. A friend of mine has Sprint on his HTC, and it is embarrassing how pitifully slow it is.

        It is horrible…. The worst I have ever used.

    Having switched to T-Mobile recently, this news doesn’t surprise me. I’ve been really impressed with LTE speeds and HD Voice.

    So are we talking just iPhones? I was seeing LTE download speeds up to 50 mbps in Orlando. I didn’t get those speeds on my iPhone 5, but come to think of it, I don’t remember speeds over 14.4 either. Hmmm
