Which phone are you anticipating more? Apple is said to be launching an iPhone 5S as early as June (and in multiple colors) to compete with the upcoming next generation Samsung Galaxy smartphone, the Galaxy S IV.
Apple is said to be improving the buggy screen of the iPhone 5 as well as the processor and the manufacturing process while Samsung will apparently be using a full HD (1920x1080) display, quad-core processor, and at least 2 GB of RAM.
Which are you anticipating more though?
