A few noob questions about using Spirit and iPod touch...

Ok so i just got a new 32gb 3gen touch and i am interested in jailbreaking it.

I use to own a iPhone 3GS that i jailbreaked with Blackrain but once i did, i would NEVER sync it with iTunes because i thought i would have issues or something would happen?

I already have it setup with my music, apps, pics, etc in iTunes on my Macbook.

Now, With that said. I believe i have to do a restore, which will wipe everything if i am not mistaken, ok not a problem.

Questions...

1) Once i restore it, then jailbreak it, Will i be able to go into iTunes and sync all my apps, pics, music, etc without any issues? ( since its jailbroken i am not sure if iTunes will allow me to sync? will it? )

2) Can i still purchase apps thru itunes as i normally would?

3) Is there anything "Different" i have to do once i jailbreak the touch? Can i just simply sync with itunes like a i always do, delete, edit and add stuff, etc, etc...

4) are there any NEGATIVES or KNOWN ISSUES about the Spirit jailbreak that i should know about?

Thanks for your help!
