To answer your question, yes. However if you have a backup, you can restore from it and get your data back.
its all deleted. if its backed up on ur comp, just re download. otherwise, just log into the itunes account u used to purchase all the stuff, and repurchase the apps+songs--u will get them free if u already purchased them
Thats true, but I had so many songs and apps its going to be such a hassle. Plus all my save files >.<
Makes no sense. You may not get your save files back, but you should still have music in your library you can sync.
u better start redownloading.......and no never jailbreak I hope you have learned a good lesson from this
if you restore you should be able to put all your purchased apps back on, BUT I'm pretty sure you will lose your saved game data (even if iTunes backed up your stuff I think)
