What is ARMv7?
It's a new CPU architecture of iPhone. Make some apps run faster.
What does ARMv7 to do with me?
Here is a post by most_Unique found on iPhoneCake.
Most apps today use FAT binary which cracked on ARMv7 device will not work on ARMv6 device.
ARMv7 = iPhone
3GS/4, iPod 3G, iPad
ARMv6 = iPhone 2G/3G, iPod 1G/2G
Most crackers, like me, have 3GS. This means when cracking any app it will not work on ARMv6 devices. We have tried to fix it but haven't yet been able to.
Now to my understanding apps cracked with ARMv6 device will work on any device. But since most of us have already upgraded some of you with older devices are just stuck. Sorry.
So if an app crashes and you have one of these old devices it is likely the app has FAT binary and that is the problem.
