i got my ipad 2 in may version 4.3.3 - and my husband got his in aug 4.3.5
i synced his to my PC without issue so we could share apps and it worked.
the camera connection kit (sd card slot and usp) both work fine on his but not on mine. (i had never tried it until he put all of our pics on his)
thinking it was a version issue, i just today synced mine with my i tunes to update my version to 4.3.5 - the update went fine - but the connection kit still doesn't work on mine.
for the record - i charge my ipad though a wall outlet (never through my PC) - so it's not a damaged port.
when i first got mine - a tech friend - who sinced moved away - set up my itunes accout and synced my ipad to it -(my PC is windows 7 64 bit) - and after he did that in the photos of my ipad 2 are two albums - the Camera Roll and another "album" called ipad2 backup which i somehow think is the problem. i cannot delete this ipad2 backup album from my ipad and i can't even find the album in i tunes.
however on my PC in photos I did find the 2 photo albums one is called ipad2 backup -the other is ipod photo cache but i don't know which if any to delete.
sorry for the long post but i think it's best to give you all the info i know.
i'm not the most computer savvy person, so your help would be greatly appreciated.
and i just realized i don't know where an answer to this post would appear!
