Apple Code Found to be Throttling iPhone and iPad Cellular Data Speeds
A website which was dedicated to providing iPhone carrier hacks claims to have discovered code in versions of Apple’s iOS that suggests the nation’s top three carriers are purposely throttling iPhone and iPad data speeds for all customers. According to developer Joseph Brown, operator of iTweakiOS, there is specialized code that exists on iPhones and iPads operating on AT&T, Sprint, and Verizon which limits the devices’ network settings to effectively cap data bandwidth.
Brown has taken snapshots of the iOS code that is managing the three carriers’ network settings as applied to an iPhone 5, all of which appear to hamstring the handset’s cellular data capabilities. For example, an AT&T iPhone 5 was limited to HSDPA “Category 10,” which tops out at 14.4 Mbps. The second largest U.S. carrier’s network is capable of supporting up to HSDPA+ speeds that reaches 21.1 Mbps.
As far as Verizon goes, Brown found throttling code on the telecom’s versions of the iPhone and iPad relating to its 4G LTE network. Sprint doesn’t have limitations enabled for its high-speed data offerings. Apple devices running on the 3G networks owned by both Verizon and Sprint, however, are also affected by similar limitations. Since Apple is in complete control of the code running all of its devices, it can be posited that the company instituted the bandwidth caps at the behest of its partner carriers.
Brown mentioned the following:
[…] from previous statements released by AT&T and many tech orginizations [sic], iPhones are very complex devices with a very complex OS. The OS eats much more data, even when in idle mode, than most phones on the market. So by carrier request, Apple limits devices to 'even out' the network, even if it means Galaxy users outperform Apple devices by such large scales.
Have any of you felt like your speed has been throttled?

I live in the uk and am on t-mobile I have a good 4 bar 3g signal at my house yet my speed varies between 15mbs and 500kbs. It isn't the signal for sure so it must be t-mobile slowing me down.

Hey, got a deal for ya!! I'll sell you a $250K Lamborghini and you might reach it's top speed as long as there are no other Lambroghini's on the road that day.
Sound kind of ridiculous huh?

Wow, SPIN IT..JUST SPIN IT!! I live in the Seattle area and have noticed HUGE variances in my data speed irrelevant of the time of day. I can tell you it is a serious problem! I pay REAL MONEY for my data stream and should get REAL PERFORMANCE irregardless of any other variables.

Any contract iPhone or any other phone will be caped

So when are the jailbreak dev's going to release a tweak in Cydia that will thwart the throttling code?
I'd be interested to see if it can be removed, and if speeds would actually improve, as I am on the Verizon unlimited data plan with my iPhone 5...
It sounds from the article like only Verizon is throttling 3G & LTE (as they have no "4G"), while the others are throttling 3G & non-LTE 4G. I would love to see something released in Cydia to test this out and see if my speeds would improve. I generally seem to get lower speeds than I see posted from others, but am in a relatively congested area with a ton of Verizon customers. I still get around 20/20 consistently, however, so it's still fast enough; but I would love to get the full force of what I pay so much for!

Lol isteveo. Nobody has 4g. They ALL have lte.
Helipilot, cars are usually limited by other cars on the road. You hadn't noticed? It's called traffic. Great analogy lol

So how do we remove this code?

Here's something to be sure of: Since it doesn't currently exist, you can't possibly have it.
