well yaar i recommend getting it JB'ed from a pro cause it will be risk free that way as far as 3g itunes and wifi goes and i can speak only for the iphone 3G they do work perfectly after the exploit and all you apps sync perfectly on thing under no circumstances should you update your Ipad unless you know for a fact this the new firmware is hackable otherwise you will have a ipad with is just as pretty as a 100rs paper weight.
