Currently, CLIQ is running on Android 1.5. CLIQ seems going through though time on their upgrade. Motorola has decided to delay their upgrade 2.1 on CLIQ.
Their main reason in this matter is that they want the consumers to experience the best in some keys area. However, Motorola are trying their best to progress this as soon as possible. Good luck Motorola!
