Can you please be specific as too how much there is an increase in speed in terms of KB/sec?
Well, Class 32 EDGE can retain speed upto 296kbps whereas Class 10 EDGE can only retain upto 236kbps.......
Same is with Class 32 GPRS which can retain speed upto 107kbps whereas Class 10 GPRS will only retain speed upto 48kbps......
Anyways, in India it doesn't make any difference......You are surely not going to get 29.5 KB/s (236kbps) on Class 10 EDGE phone and even not get the same speed on a Class 32 EDGE fone.....
