I have bought iball slide i6012. I thought it would be nice tablet but it is not. Worst tablet ever only support iball and ideas dongle only.
If internet want to be used in it then only wifi and 3g. 2g is not working ever in this tablet.
And about there service, once the tablets IC has burnt so I go to service center and they took about 1 month for replacing the IC. After that the screen pixels were not good so it took more 15 days to replacing the screen.
Iball should only make computer accessories not mobiles and tablets.
