I'm currently working on a piece of software for sending Nokia ringtones (OTA) in both GSM (European) and TDMA/CDMA/GSM (US) networks. Is there any difference in the OTA format as such between the three?
If GSM alone, no issues for me. I understand from Nokia Smart Messaging spec that GSM - 8 bit and TDMA - 7 bit.
If so, where should I need to do conversion (GSM / TDMA / CDMA) based formats.
