I am in Pakistan, and I am using the EVO Design 4G (Sprint) on GSM for over a month now. Works brilliantly !!
What I am working on is to have the CDMA module register with one of the local EV-DO and/or WiMAX service providers. I have an account with both local operators, therefore have all the necessary settings. If anyone can guide me how to set up the phone I'll be grateful.
