I found that the screenshots you take with your iPad (I have version one not iPad2) go to your Camera Roll. I haven't time to try it out this morning, but in order to use your screenshots you need to transfer them to a Mac or PC and use them from there.
Connecting to Public Networks
I find that taking my iPad between home and work confuses the iPad, and it doesn't just detect the new network and away we go.
At the library, I need to go to Settings/General/Reset Network Settings. Then, I need to open Safari ( a new session of it because it gets stuck on a previous sesion for some reason, agree to our user agreement, and all is well.
When I come back home, I have to do this again, then sign back in to my home network with a password.
Cumbersome, but other solutions I Googled got me nowhere.
On the plus side, it didn't make me sign in to iTunes to do any of this.
