Hello, I got a few questions before I jailbreak: a) Does the iPod Touch become glitchy and unstable when the iPod Touch has been jailbreaked and installed with 3rd party apps? b) Is easy to install iPhone applications (i.e. Mail, Notes, Maps, Weather) to my iPod Touch once its jailbreaked? c) Will Apple's new updates brick my iPod Touch? Is there any way I can prevent it from bricking my iPod? Please let me know. Thanks, I appreciate it.
