The app contains several books already, you can add it or remove it using iTunes File Sharing or WiFi File Sharing.

Lite Version coming soon…

On some tutorials on the net, people not using protocol for delegate, but I want it to be protocol based delegate.

So, here are the codes:

DBDelegate:

@end


Then, on my DBManager:

@protocol DBDelegate;

@property (nonatomic, assign) id <DBDelegate> delegate;
@end


It used to be “id delegate”, but since we are making a protocol based delegate, we must make sure that our delegate object conforms to DBDelegate protocol, by using conformance statement of id, this way we don’t need to check if a delegate is conforms to DBDelegate or not.

On the codes where we fetch the records, we can call the delegate:

if (self.delegate)
{
[self.delegate dbGotBookInfoRecord:file Statement:stmt];
}


That’s it we now ready to use the delegate

Looking around for a good uninstaller, I found Final Uninstaller, but the thing is a shareware.

First, I was going to alter the registration process, but then everytime I fired up Final Uninstaller, I always have UnRegistered version coming up, even after I patched the Registration process. Then I changed my trace into the application start, and look for some string reference of “UnRegistered Version”, if I can’t find it, I will look intermodular calls and reverse engineer some assembly codes to perhaps make a Keygen, based on the Registration process, but I found this string, and everything become simpler, I can then crack it for just a couple minutes.

Fired up OllyDbg, search for strings reference of “UnRegistered Version”, trace up and search for the caller of the unregistered function, got one, changed jnz into jz, and voila, I have a patch address, fired up hex editor, change patch it, save it as a patch binary. Overwrite my trial one with my patched one, then it’s full version now.

This app is bare naked, it doesn’t have protection whatsoever that makes it easier to crack in just a couple minutes.

One more thing, this app created either using Delphi or C++ builder, I saw it uses fastcall calling convention in all of its function call and TXXX class naming everywhere.

Figure I could generate the serial number using my iPhone, so I fired up Xcode, patch it again (I was reinstalling Snow Leopard), and spent a couple minutes make some scrollable view and build.

Now I have my own serial number generator for my products right in the palm of my hand, I can take it everywhere without having to bring along laptop.

It’s working for iOS 4.0.1 using 3.1.3 SDK, all I have to do is reread my post about live debugging then do the hard way by packaging the ipa file myself on iOS 4.0.1. But hey, it works.

But no matter, if you open Cydia, it will automatically save your SHSHs into a file in its server, so bypassing Apple signature server is OK if you already has SHSH on Cydia.
Just read the Restore Error post before.

Hit is big, 177 for a day, seems you guys also has the same problem with me…

1. Just open Cydia,
2. Then goto more package sources.
3. Install iPhoneModding
4. Go to search tab, and search for “Push Fix”, you should see it from iPhoneModding below the title.
5. Install it
6. Reboot Device.
7. Voila, Youtube now working, Push Notification, etc fixed.

Sadly enough, for you guys who wanted to erase or restore your iPhone 3G into iOS 4 using iTunes 9.2 will be out of luck, since Apple is no longer signing the version 4.0 anymore. Instead if you insist on restoring your iPhone 3G into iOS 4.0 instead of 4.0.1, you’ll have error 3194 on iTunes saying that your Device is not eligible for this build, bla.. bla..

This is unfortunate, you can not upgrade your iPhone 3G officially, but.

You can still restore it unofficially.
Basically when iTunes showing “Verifying with Apple bla…”, that means iTunes is checking for signature from Apple’s signature server. And guess what, Apple no longer sign your iOS 4.0 firmware which makes your device is not elligible for restore, unless you update with iOS 4.0.1, this is one way for apple to force its customer to upgrade into the latest firmware, so all hacks will be elliminated if one is provided in Apple’s latest firmware version.

Now, we can bypass this signature checking when iTunes contacting Apple by changing the server from Apple’s Signature Server into Cydia’s clone of Apple Server.

It’s easy (for Windows):
1. Fired up your cmd.exe, and make sure you have administrator privileges.
2. Type this is: CD \WINDOWS\SYSTEM32\DRIVERS\ETC
3. Type this: edit hosts
4. Add this to the last line: 74.208.10.249 gs.apple.com
5. [UPDATE]: Save the file (People asked me to add this, it’s a common knowledge tho when you change a file you must save it)
6. Restart your iTunes.
7. Put your iPhone 3G in recovery mode, by turn off the device first and pull the plug from your PC. Then press Home Button and connect your iPhone into your PC, then wait until the Recovery Icon shows up (iTunes icon with cable above it).
8. Now, restore your iPhone with your firmware iOS 4.0 (in windows using Shift + Restore, in mac using Options + Restore)
9. Voila, it will be restored succesfully, it’s fully working on my iPhone 3G.

You should notice the number 4 step is the bypass server, by pointing Apple Authentication domain into Cydia’s Server IP Address, this is trivial in unix, and thankfully, we can do this in Windows.

On Mac, it’s the same, except for the cmd.exe and the cd thing should be into /etc/hosts…

Enjoy your Jailbreak Restore…

[UPDATE]
The use of Cydia server doesn’t need you to download any software, but if you still having error using Cydia server, you can download TinyUmbrella from thefirmwareumbrella.blogspot.com

You can then start its TSS server and replace the step number 4 with :

127.0.0.1 gs.apple.com

And still on the very same hosts file. Some people called it stupid, but this is simple way to bypass the iTunes from connecting to the real Apple Server, if you have better way to do this, just tell me…

1. Cydia
2. MobileSubstrate
3. UIKit Tools

Just update Cydia to the newest version, and it’ll be OK.
