How to make most tweaks and apps work with iOS 7 on pre-A7 devices

Are you jailbroken on iOS 7? Are the apps and tweaks installed via Cydia not showing up on your device? If you’re running into this problem, you’re not alone. I’ve received numerous questions about this problem over the last few days; so many, that I thought it would good to make a post and video on it for those that need help.

The short answer to the question is Mobile Substrate. Most of the apps and tweaks that you install from Cydia rely on Mobile Substrate, and Mobile Substrate has not been updated for the latest iOS 7 jailbreak as of yet. An update has been promised to come soon, but Saurik, its developer, is no doubt inundated with about a thousand and one different tasks related to the just released jailbreak.

Let’s give Saurik the time he needs to get a properly updated working release of Mobile Substrate in our hands. In the meantime, if you’re running a non-64-bit device, you can take the following steps to make your favorite apps and tweaks work.

Apple testing non-Retina iPad mini with A6 chip, iOS 7 SDK references suggest

Despite Google’s recently refreshed Nexus 7 now boasting a Retina-class 1,920-by-1,200 pixel resolution screen (check out Jeff’s awesome Nexus 7 vs. iPad mini video showdown), Apple’s seven-inch iPad mini by contrast remains stuck with the rather pedestrian 1,024-by-768 pixel screen.

And now, seemingly corroborating a flurry of rumors pointing to a Retina iPad mini upgrade in 2014, references a developer discovered in the iOS 7 SDK suggest Apple has been testing a new iPad mini with a faster A6 chip, but without a Retina display…

Apple and Samsung might not be best frenemies forever

Apple is quickly cutting its ties to Samsung, moving from a bizarre frenemy relationship to a “one-dimensional” acquaintance. The iPhone 5’s A6 chip marked the first time the Cupertino, Calif. company did all the designing and the South Korean rival simply manufactured the silicon.

The relationship between the two companies is “about to become one-dimensional,” writes The Korea Time, citing a Samsung source. For some time, Apple and Samsung have been technology’s odd couple, one day suing each other and the next cooperating to design and build chips for the iPhone…

The iPhone 5’s A6 processor can dynamically vary its clock speed for performance

The A6 chip which debuted on the iPhone 5 earlier this month can do some pretty clever tricks, stemming from a heavily customized ARMv7 design. Benchmark data suggests that the A6 can dynamically overclock itself to up to 1.3GHz and downclock to just 500MHz, depending on workload.

This is nothing new in chip design, of course (just ask Nvidia or Qualcomm). But given that Apple designs its chips in-house based on ARM and Imagination Technologies blueprints, it shows just how far along Cupertino is versus companies that use off-the-shelf chips which are not as power or performance-efficient as the A6…

Samsung-made A6 chip has dual ARM CPU cores, 3 PowerVR GPU cores, 1GB RAM

Apple claims the iPhone 5 is twice as fast as the iPhone 4S (which is no slouch) in terms of processing and graphics power, thanks to the in-house designed A6 chip. You could even say that the A6 pushes the iPhone 5 ahead of competing smartphones, at least in Javascript and Geekbench tests.

The A6 is clearly a beast of a chip, not just in terms of sheer power but also in delivering the world’s first phone powered by ARM’s Cortex-A15 CPU platform, completely customized to Apple’s needs. In addition to two CPU cores, the first diffusion image by UBM TechInsights has also showed three GPUs.

And now, repair wizards iFixit teamed up with chip experts Chipworks who put the A6 silicon under a sophisticated microscope. Here’s what we could glean from so-called “floorplans”…

New A6 chip confirmed to have three GPU cores

The iPhone 5 launched yesterday, and first impressions seem to be in line with the early reviews: the thing is fast. As most of you know, Apple custom-built an all-new processor for the handset called the A6.

Now that the phone is available, we expect to learn more about the new chip as teardown experts continue to rip the device apart. In fact, a new tidbit has already surfaced: the A6 has triple-core graphics…

iPhone 5 finishes first in SunSpider Javascript performance test

The iPhone 5, sporting Apple’s custom A6 processor, is really turning some heads in the tech world. Last week it beat out the competition in Geekbench tests, and early reviews say the handset is extremely fast.

And the accolades don’t stop there. The first SunSpider Javascript benchmark, which measures Javascript performance, for the iPhone 5 was published last night. And again, Apple’s smartphone swept the field…

iPhone 5 rules competitive landscape in first Geekbench tests

Following a detailed analysis by AnandTech which exposed the A6 chip inside the iPhone 5 as bein comprised of custom ARMv7 design rather than stock Cortex-A15 cores, someone has posted an iPhone 5 benchmark on Geekbench.

Now, the handset will hit store shelves on Friday so there’s no way to verify the authenticity of this poster (and Geekbench scores could be easily faked). If you believe the results though, the iPhone 5,2 hardware has a Geekbench score of 1601.

The test also shows an ARMv7 processor design with two cores clocked at 1.02GHz each, with 32KB of L1 instruction/data cache, 1MB of L2 cache and 1GB of RAM (Samsung’s print ad has helped reveal that tidbit)…

iPhone 5 found to have 1GB of RAM, custom processor

As usual, Apple didn’t give us many details regarding the internals of the iPhone 5 outside of what it lists on the handset’s Features page. We know it has an A6 processor, but that’s about it.

Luckily, some smart folks have done some digging and have uncovered some interesting information about Apple’s new smartphone. For instance, they’ve confirmed it has 1GB of RAM…

Apple could be close to shifting CPU orders away from Samsung

The iPhone 5 comes with a brand new Apple-designed A6 chip for a twofold jump in CPU/GPU performance. In fact, the iPhone 5 could easily be the first ARM Cortex-A15 smartphone on the market. The A6 is likely manufactured on Samsung’s 32-nanometer process, but probably not for long as Apple has been looking to take its chip contract elsewhere.

There ain’t many places to go: Intel sucks at power management and Samsung is #2 chip vendor in the world. Taiwan Semiconductor Manufacturing Company (TSMC), however, is the world’s largest dedicated independent semiconductor foundry and Apple could be closer than previously thought to shifting production contracts away from Samsung and towards TSMC.

Can you say “stock plunge”?

A concise iPhone 5 hardware overview

We’ve already brought you a truck load of coverage from today’s iPhone 5 event, so how about a concise wrap-up of the iPhone 5’s hardware features as a night cap?

What do you think? Are you satisfied with Apple’s hardware offerings for the iPhone 5?

Apple’s new A6 chip runs two ARM Cortex A15 cores, quad-core GPU

Surprisingly enough, the iPhone 5 comes with Apple’s in-house A6 chip (labeled “S5L8950X”) rather than a souped up version of the A5X chip, as previously thought. Apple’s Tech Specs page for the iPhone 5 doesn’t even mention the A6 (a norm for Cupertino). The Compare iPhones page names the chip, however without divulging an iota about its architectural underpinnings.

Likewise, Apple executives at today’s presser shied away from going into the technicalities like core counts and clock speeds and would only mention a twofold jump in CPU and GPU performance. It would nonetheless appear Apple has beaten the likes of Samsung and Texas Instruments in delivering the world’s first phone powered by ARM’s Cortex A15 CPU platform…
