Have to say that find this a strange comparison choice between keypad device running outdated Symbian and touchscreen dual SIM device restricted to JAVA applications. You don't mention whether presence or absence of WiFi is of importance and in this price banding I would look at Asha 501.
If i have helped at all a click on the white star below would be nice thanks.
@scoobyman: will this really works with applications like WhatsApp which runs and connect internet in background?
Unfortunately not as WhatsApp makes it's own access irrespective of global device settings.
