Book in iBooks on Pad2 but not in iBooks on iPhone4S

[TurboTiger]

Just downloaded my first book through iBooks/iTunes using my iPad2.
The book appears in iBooks on my iPad2 but not in iBooks on my iPhone 4S.
I have all settings on both devices to sync iBooks.
I've deleted and reinstalled iBooks on my iPhone 4S.
I've turned Both device off and then on.

Any help would be appreciated.

TIA

Nevermind, I went to iTunes on my 4s and downloaded it there.
Now both devices are in sync
Tks anyway
