BlackBerry and TCL have teased the KEYone for nearly half a year, and now Americans can finally see what all the fuss is about without jumping through hoops. The two have revealed that unlocked, US-friendly variants of the Android-powered BlackBerry will be available at both Amazon and Best Buy on May 31st. Spend $550 and you'll get the phone in either a GSM-tuned version (for the likes of AT&T and T-Mobile) or, if you shop at Amazon, a CDMA model optimized for Verizon. If that up-front price is just too much, Sprint and other carriers should offer the KEYone this summer.
