We’re on the update trail again. Today it’s a “Car Kit Mode function enhancement” for the HTC HD2. The update…
“..enhances the native Car Kit Mode functionality. This update includes the ability to allow the phone to stay natively in Portrait mode so you are given the option of flipping to a horizontal view or staying vertical. Also included are call history view expanded, allowing the dialer to dial “+” in the recent call menu, and providing more flexibility in completing messages while using Bluetooth.”
This should be just patch, so it shouldn’t delete any data.
