After a software update was done using iTunes for my iPhone 4, I could not add schedules in my calendar anymore. I have upgraded my iPhone 4 to iOS 5.

The plus (+) icon is not visible anymore which was located on right-most top of the screen. I can still update my existing entries but I could not add another schedule.

Any kind of help will be much appreciated.

I already have an iPad 2, and just recently, I bought my first iPhone 4. After I got my iPhone, I plugged it immediately into my computer and tried to synchronize some of the applications, which I had in iPad 2. I did this through checking and choosing the icons of the applications in iTunes Apps screen.

Just now, I have upgraded my iPad 2 into iOS 5. My applications were deleted from the iPad just as I have expected, after I upgraded into iOS 5. Luckily, I have stored all of my apps into the iTunes so I just plugged in my iPad again and have it synched in iTunes. All of my apps were back though I have to organize some folders agian.
