For those of us with big sticky thumbs, typing on the iPhone can be a great test of patience. Although I don’t plan on trading in my iPhone I do miss the tactile sensation of actual keys when typing. 4i Concepts’ Thumbs2 is a perfect solution to this. Small ridges gently overlay letters to guide your thumbs through the QWERTY keyboard. It does all this without blocking any portion of the screen. It is removable and can be stored on the back of the phone when not in use. Also available is a bumper to hold it in place on a more permanent basis. It comes in both portrait and landscape versions.
Keypad alone is $12.95. With a compatible bumper is $24.95. See 4i for more details.
