We’re not sure why HTC decided to change the name of its ChaCha handset in Spain. Maybe it’s the fact that ChaCha is already the registered trademark of a mobile search engine? Or maybe it’s that “chacha” slang for “servant” or “slave” in Spanish? Whatever the reason, HTC has decided that its Facebook-button bearing, ChaCha handset — which could be making its way to AT&T this summer — will be known as the ChaChaCha in España. Earlier today, the company took to Twitter to let Spaniards know about the name change. What do you think? Are three chas better than two?
