Apple has just released iTunes 10.2.1, which brings nothing new that we now of from iTunes 10.2 The description reads exactly like the one released for 10.2.
So, what does it bring? It’s definitely just a bug fix release, though we aren’t sure exactly what bug that fixes.
iTunes 10.2 was released just last Wednesday after the iPad 2 event, so it is strange that Apple has rushed this update and has released it in less than a week.
No word on how it will affect syncing with a jailbroken device yet, so it may be better to hold off until we know.
