Yes, you can bring a jailbroken iPod, iPhone, iPad, etc. into the Apple store and get it checked out. They 99% will give you a new product.
No, but as long as you restore it if it has a problem, then apple can't see that you have jailbroken it.
unless your ipod is jailbroken you wont be able to download app from anywhere out of the apple app store
Yes it can.
A jailbroken ipod is legal, and getting jailbroken aps is legal too. But, getting cracked apps (apps which you usually pay for, but you can download for free) is illegal. Eventhough jailbreaking is legal, if you take a jailbroen ipod to an apple store, they won't like it
You can; use the App Store. Alternatively if your iPad is jailbroken you can also use Cydia to download applications that Apple wouldn't ever approve for their own store.
If it is an iTouch, iPod, etc, you cannot take it to an Apple store to get fixed, updated, etc. as they do not accept jailbroken devices.
The iPod screen may have crashed on an applications splash-screen. To fix this, simply do a soft-reset. Press the home and sleep button simultaneously for around 5 seconds. Your iPod should restard. If not, take it into an Apple Store for further examination.N.B. If your iPod is jailbroken, it cannot be seen by an Apple Store! When jailbroken, all warranties automatically expire and you will have to pay to get it fixed.
bring it in to an apple store
Bring it to an Apple Store.
Try making sure it's charged first or try the reset feature first. If there really is a problem with it but it's jailbroken, the apple warranty is immediately gone and apple most likely will not fix it.
They will send it back unrepaired because they don't repait jailbroken iDevices.
Yes, but only on jailbroken devices. Apple does not permit such applications in the App Store, but there are applications on the Cydia app store that do permit keylogging. Or you can try third party software like iPad keylogger.
