no its not actually its recommended
Yes, updating the software of an iPod undoes the Jailbreak.
It does not, unless the update is interrupted or, you restore instead of update.
nope
easy by upgrading to windows xp :-)
If you have an Ipod Touch 2g and you upgrade to 3g by using itunes and the ipod is not jailbroken you have every thing when your are done upgrading...!
if you meen Ipod Touch 2G upgrading to 3G it is Bluetooth and the Search Page! if you meen Ipod Touch 2G and the new Ipod Touch 3G it is the 64gb and voice control!
It depends on what you are upgrading. If you are upgrading the hard drive or generation to a higher generation or hard drive capacity, then it will cost you money. If you are upgrading the software, it will only cost money if you are buying the 3.0 or 3.1 software.
Yes it is.
The iPod Touch 3G in incapable of taking pictures because it has no camera. If you really want to take pictures with your iPod i suggest upgrading to the iPod Touch 4G as it DOES have a camera built in. Two in fact.
Apple will replace the exact model of the iPod that is scratched, per your warranty agreement. If you want to update your model of iPod you can do so, but you will pay extra for upgrading.
It depends what you want in an Ipod. If you want to play games and listen to music there is not much point in upgrading. But if you plan to take advantage of the iPod's camera features, then it is a well worth upgrade. If you own a 2nd generation iPod touch, you will have a much faster experience, smoother apps, and take advantage of features like multitasking. Overall, it is up to you. Update: You may want to wait for the 5th gen iPod from this point because it is supposed to come out very soon.
