Guys if you are driving, please do not "text". And please, do not try to make a call unless you have it in your speed deal, looking in your contacts will distract you and eventually you may have an accident. But here is a solution, Talking Touch Dialer allows you to navigate in your contacts with very little distraction because it reads the contacts for you, once you find the one that you are looking for, with just a gesture it dials it for you.
You can watch a demo here, it's in Spanish but I can tell you, the program speaks in English better than me!
You can find it in the Android Market using this barcode:
