附註 Cupacake 有關 Radio & Telephony的更新

* New features
o SIM Application Toolkit 1.0.（SIM 卡的 App 工具箱）
o Green CALL button is no longer a shortcut for "add a new call". This has been a rarely used feature and confusing if triggered accidentally.（通話鍵不再是「add a new call」的捷徑，預防誤觸通話鍵）
o Longer in-call screen timeout when using the speakerphone.（加長來電的「timeout」時間，當使用「speakerphone」的時候）
o "Show dialpad" / "Hide dialpad" item added to the in-call menu, to make it easier to discover the DTMF dialpad.（來電時增加「"Show dialpad" / "Hide dialpad"」的功能）

* Significant bug fixes
o An obscure case where the Phone UI could cause the device to not go to sleep on its own. This would happen if user bails out of the in-call screen by hitting HOME, followed by the call disconnecting remotely.
o Don't allow a single tap to open the in-call dialpad. It is now required to touch and drag it. This makes it much harder to accidentally open the dialpad by touching the screen with your face.
