iPod Touch 4G Jailbreak Disadvantages and Risk Factor

There are lot of people curious about the disadvantages or risks involved in jailbreaking the iPhone or iPod Touch, before they actually decide to do that.

Well, there is a very very slim chance that you can brick your iPhone or iPod Touch. Which basically means rendering it unresponsive. But those are usually fixed by doing a reset (press and hold the home and sleep buttons at the same time). You can then reinstall the firmware and try again.

Doing the research might set you back 20 minutes or so and the whole process might take another 15 minutes. If you ever take it back to Apple for warranty, you probably don’t want them to see that you’ve jailbroken it so you might spend another 10 minutes doing a firmware restore through iTunes to set your iPhone or iPod Touch back to its original settings.
