I run the Secret Cities facebook sites and i am in the process of looking to connect the information to mobile phone users in a useful way. How or where can i find out which phones systems to target? as i cant afford to do them all. Nokia is easy as they have a wizard that works really well and doesnt cost a dime !! just time
but what else ? Iphone Blackberry android ? which phone system is getting used the most by city dwellers?
