I am pretty sure you can!
An iPod touch 4th gen features similar things as previous iPods, only that this iPod has a camera; wich lets you record videos & take pictures. Another new feature is that it has GameCenter.
Yes and no. According to those who did jailbreak their iPod Touch, they say it is safe to do it. Though, the hardcore facts say that is isn't safe because it voids your warranty, and could cause software corruption in your iPod and could possibly make your iPod useless. It is a risk to jailbreak your iPod Touch, but according to those who did it, if you do it correctly it is safe.
What exactly do you mean by safe... Can the iPod touch get viruses from websites? No. Does the iPod Touch have small pieces that can break off and be swallowed by a small child? No. Will the iPod Touch wake up in the middle of the night, sneak through the house and steal your wallet?... I highly doubt it. iPod Touch has stable software that is not invasive or damaging to your computer in anyway. I have been using my iPod Touch 3G since they came out and have never had any problems with it.
Yes because I've done it :)
There are ways to get free games by jailbreaking your iPod touch, however be warned because this is not legal and you can get in serious trouble with Apple. Also, these games are most likely emulated, meaning they are not the games themselves, but extremely close representations of the games that might not run correctly, and will not work with GameCenter.
As of today (November 24th, 2010), jailbreaking an iPod Touch is not illegal. Is it 100% safe? No.
You have to connect your iPod / iPad / iPhone to your computer and update it. The app will automatically arrive.
Wi-Fi is completely secure for your iPod Touch. It would be best if you have a locked router that needs a password, but it is completely safe.
Yes.. But the hotness that it makes can burn the hardware of your iPod so.. Its your choice...
on an iPod touch, if Springboard crashes, it'll reset your iPod and put it into safe mode. Like a computer goes into when it crashes and you restart it. The only difference is that you can work with ANYTHING in safe mode on your ipod touch, which is necessarily the iPods state after springboard crashing.
Probably because I do it all the time...
