I have the same problem with the Shinhan Bank app. It detects if your phone is jailbroken and won't run if it is. If you are successful with the KEB app, could you give the Shinhan Bank app a go as well???

ugh..
this is annoying.
If I jailbreak it.. I can't run my KEB application. It no longer trusts the platform.
So just a heads up if you are using your Korean banks iPhone app you might not be able to use it if you jailbreak it. |
What is the name of the KEB application? I think that it might be a simple check that could easily be overridden with a mobile substrate plugin. If you give me the name, I'll download it and see if I can write up the plugin. |
Just search for "KEB" you should find it. It's got the KEB bank logo on the icon. KEB letters with a blue and red thing that looks like maybe wings or something |
Well, I spent some time trying to reverse engineer the application by disassembling the program and searching for the message that pops up, but that was pretty tough so I gave up really quickly. Then all of a sudden today, I thought of an incredibly easy method of circumventing the check.
What I ended up doing was creating a mobile substrate plugin that hooks all [UIAlertView show] messages in the KEB application (the "pop-up" window is an UIAlertView). If the UIAlertView message is equal to "단말기의 OS변형이 의심되어 프로그램을 실행할 수 없습니다." then the [UIAlertView show] message is spoofed so the pop-up doesn't get called. Since the program exits when you click the "확인" button on the UIAlertView, if the UIAlertView doesn't show, the program doesn't exit.
I tested this on both an iPad running 3.2 and iPhone 3G running OS 4.0.1. It worked on both of those, so I think it shouldn't be any problem on any other iOS device. If you have a problem, let me know.
The instructions for using this are as follows (you must have MobileSubstrate installed, most jailbroken phones and iPads should have this already):
0) Close the KEB program (shouldn't be required, but I had some problems with this)
1) Download the KEBBankSpoofer.dylib here: http://www.mediafire.com/?qml1m1yva8w5ac4
2) Use an SFTP or file manager program to put the file on your phone at /Library/MobileSubstrate/DynamicLibraries
3) Restart the KEB application
That's it. You should be able to use the KEB iPhone application with jailbroken iPhones now. I've included the source below. It's a really simple file.

Well, I just did the Shinhan Bank application the same way. Follow the same instructions as above for KEB, but use the following file:

Anyday now I'm waiting for Apple to update the iPhones "over the air" and brick all the ones that are jailbroken.
Kinda like when Microsoft brings down the Ban hammer on Xbox Live. Or when Blizzard does the same with WoW accounts.
They wait until they get as many people as possible and then drop the hammer at one time.
A lot of people would be pissed, but then again, Apple did make it blatantly clear they don't want people to jailbreak. |
Won't happen as in the US it has been deemed LEGAL to jailbreak the phone. If Apple did such a thing without notice it would totally lose its market. I bet anyone with a brick would never buy another Apple product again.
On another note: I now know why my KB app won't work...my phone is jailbroken. |

Tatertot,
Any chance you could work your magic on the Samsung Card app? I get a similar message and then the app quits. |

Hey, sorry, I've made some changes to my programming setup. Right now I don't have proper tools to make jailbroken apps. Sorry! |

| Tatertot... I tried your mobilesubstrate plugin but it doesn't seem to be working anymore on either iphone/ipad 4.3.3. Maybe it needs a little tweaking? Any chance you can look at it? Thanks! |

Hmmm....looks like KEB has updated their app - it's now "M" banking or something. Anyway, the workaround you provided doesn't seem to work with it. :(
Any chance of an update? |

| I jailbroke my wife's Iphone 3GS using Greenpoison and now she can't use KB banking. Is there any way around this? With Android, you can switch root access on/off very easily, but I can't find a way to do it on the Iphone.. |
