Can people that are using BTL's (GPRS) or Smart's (CDMA) data service, please give some feedback? I am not talking about Smart's internet service. I'm talking about data service for phones, that gives you email and web (and phone) on a smartphone/pda. How is the coverage, what phones are people using (treo, blackberry?)... Thinking about going with BTL's service soon, just want some customer reference.
