well i would go for gsm.
@drgrudge i think there is some problem with cdma batteries,
else there is some problem with samsung and lg cdma phones.
coz i haved used samsung slim and lg 3 models already and my friend uses the moonlight model and we all have a single BIG problem- Battery!!!!
i had to recharge my cell everyday from the very first day after just 20-30 mins of talk.
and the same samsung slim in the Gsm segment
does last upto 2-3days !!!!
this is strange or else there is some probs with the cdma.
another factor with cdma- u are stck with the same service provider!!!
if u want to change u got to get a new cell.(now thats a real big advantage for the GSM users if u get dissatisfied with ur service provider.)

and yes there are not too many users and providers in India in the cdma segment as compared to the Many prevailing companies well trusted with thier service in the GSm sector.
so for now i think going for Gsm would be a more viable option.and

yes another point is as cdma is not all that wide spread as its counterpart, the network wont be available at all places.

the network is still not available at all places even for Gsm sets but they do cover atleast much wider coverage than cdma.
