I believe the blackberry Z10 and Q10 are excellent devices however let's not forget the Blackberry Bold 9900, its a perfect smartphone which compares quite satisfactory to top ten cell phones on the market today. Its dependable, reliable, and its excellent quality. I believe with all the hype with the new Z10, Blackberry has forgotten and or neglected the Bold 9900 which got them up running and competing again. I am with Claronicaragua and own a Bold 9900 but the same 7.1 OS, no new updates for over a year.
