AT&T and battery issues aside, the compliant I hear most often about the iPhone is the handset's lack of a physical keyboard. It's difficult for many users to master the phone's touchscreen typing, even with its built-in correction. 4iThumbs wants to help. The company has developed a plastic overlay for the keyboard, which adds tactile ridges, so the user feels something akin to keys.

4iThumbs doesn't interfere with the phone's multitouch capabilities. Users can leave it onscreen while using non-typing apps, if they should so chose. The accessory is available in both portrait and landscape orientations for $14.95 and $16.95, respectively. Or you can pick up both for $19.95.
