I have my iPhone 3GS jailbroken and yesterday there is an update on Cydia called Mobile Substrate and I went ahead to update it as I always do. After the update, it asked to reboot my phone and after rebooting my phone its just stuck at the Apple Boot logo and just hangs there. I tried plugging in my phone to the computer but my iTunes doesn't detect my phone at all. What can I do? Any help? I can't use boot up my phone at all now.
Have you tried the cold reboot method? The mobile substrate thing is for cydia installer and in no way will it affect anything else. Try to recall if you did something else.
Or get a Windows Phone. :)

You must have installed an app that isn't meant for your current iPhone OS version, for example installing an app that is meant for OS3 in OS4.
Power off your iPhone, plug your iPhone into your computer with iTunes. Hold down the [] Home button and then hold down the power button to power on your iPhone. Wait until your iPhone boot pass the Apple logo, and IF your iTunes detect your iPhone, upgrade the firmware to the latest version and be a good boy and don't jailbreak it if you don't even know how to check for the apps version before you load it into your iPhone with the wrong OS.
The iTunes will not fail to detect your iPhone, if it does...then you have a hardware fault which I don't believe so.
If the iTunes is unable to upgrade your firmware to the latest because your OS is corrupted, and the firmware fails while upgrading halfway....then you either go look it up online on how to do it or you bring it down to the Apple Service centre and confessed to them what you did and hope they are willing to restore it for you.
Most probably your iTunes will be able to detect your iPhone but your firmware upgrading is likely to fail halfway.
Just be prepared lor....
