These are data services available in GSM networks.
CSD - Circuit Switched Data
HSCSD - High-speed CSD
GPRS - General Pacet Radio Service
CSD is different from GPRS, and you can use either for WAP or for any data connectivity requirement.

romeoendi, basically CSD and HSCSD are dial-up services where you pay per minute, and GPRS is an always on connection where you pay per data transferred. GPRS is also usually but not always faster and is far more popular where it is available.

& high speed data 'slows' if the network is busy - so it aint always that high speed - it usually 28/8kbps - where CSD is 9/6 speed - in comparison ur landline is 56/6 & my broadband is 530.0kbps for some strange reason - when it should only be 512.0 - numbers=bollocks.
