Did you realize that every time you create a new note, it seems to always access the internet even though you do not have any apps running in the background?
Note the network activity loading indicator on the statusbar.
Apparently, if you set up your email client (assume the mail server support IMAP), in my case gmail, it will automatically turn on syncing for notes.
So each time you modify your notes (or create/delete notes) in the default Notes app, it will save this changes to your mail server.
For example, if you are using gmail, the Notes app will create a Notes label and all the notes will be saved as entries having the Notes label. However, the process is one-directional, so you can’t modify the notes in your Gmail.
Of course, if you prefer not accessing the net and not syncing the notes, you can turn off this features in the Settings app under every email acount.
The PlayBook really looks impressive (at least in comparison with 1st generation iPad)
Android has already been ported over to iPhone 2G/3G but this few days, there has been a video which indicates that it is possible to port over Android over to iPhone4 and iPad
But the Frash package is still not stable enough (e.g. it messes up the default youtube plugin)
Somebody set up a repo with the Frash plugin and a SBSettings toggle so that you can toggle the effect of Frash.
To install Frash and the Frash toggle directly from cydia add this cydia source:
