Since my main audio device is Xperia D2105,
\nI seldom use My ipod touch 4th (iOS 5.1).<\/p>\n
You may think iPod touch 4th is obsolete,
\nbut I’m a type of person who use old device until it breaks.<\/p>\n
I heard iOS6 was too heavy for this device,
\nI kept iOS5.1 for a long time.
\nI use it as audio device, so there is no need to update iOS6.<\/p>\n
But these days many apps requires iOS6,
\nSo I finally decided to update my ipod touch 4th.<\/p>\n
But After updating it,
\nEvery operation takes much time than before!
\nHow terrible it is!<\/p>\n
I changed Language to English.
\nI have disabled almost all notifications.
\nIt became better.<\/p>\n","protected":false},"excerpt":{"rendered":"
