Today I managed to install iOS 4.0 GM on my iPhone 3GS and in what follows I will tell you about my short experience with iOS 4.0 GM. First of all, iOS 4.0 GM looks great, Apple has worked a lot on the animations and the way the icons are displayed in SpringBoard, not to mention how the folders are opened and the way the task manager for multitasking was implemented.
Secondly, iOS 4.0 is still not 100% compatible with the jailbreak solution via PwnageTool because it happened to me many times that Cydia and the phone menu got blocked, and I could no longer turn off the wireless, and the system moved with difficulty, in short, there is still work to be done on jailbreak solutions. Thirdly, MobileSubstrates do not work at all with iOS 4.0 GM, so if you have switched to the new OS, I advise you to stay away from mobilesubstrates because you might wake up with a small surprise and you will have to restore. Fourthly, Cydia tends to freeze sometimes when reloading the application lists, and if you want to install an application from Cydia, I want to inform you that you have to give a respring or restart to see the application in SpringBoard.
That's all about jailbreak for now, as I learn new things I will write other articles on this topic.
