Cuban National Statistics Office has issued their 2011 Annual Statistical Report, which includes data on information and communication technology.
The table shown here (click it to enlarge) presents physical ICT indicators. As you see, there are now over a million mobile phone subscribers. Note that Cuban subscribers do not have "smart" phones used for mobile Internet access -- their phones are limited to calls, text messages, taking pictures, etc.
The number of (often restricted) Internet users increased a little between 2009 and 2010. We always expect Internet growth, but it is surprising that the number of computers on the Net and the number of .cu domain names actually decreased slightly.
