Micromax A110 Net Connect Problem- with Reliance/Vodafone Dongle

Hi,
I just buy a new tablet from Micromax,"Micromax A110" this month. So, far the Tablet works good but the problem i was suffering is that it does not support any other Dongle for Net Connection like i had used Reliance and Vodafone Dongle it displays error and infact it is only working with TataPhoton when i called upto to the Customer Care they said that is will provide Net Connect with Tata Photon only such a crap this was. If it only support TataPhton for Net Connect than why it didn't mention it on their advertisement. If someone figure any solution to it please let me know as soon as possible.

As far as I know, tata photon issue is with Micromax funbook series only and why the hell you want to use dongle with micromax a110 when it already have 3G SIM support inbuilt ?

It is in a huge demand. Just connect it through wifi or net card, it will work. I bought it recently and it is good enough for internet use. I bought it at 9999 rupees.

I agree Yahoo..
and still question is why someone want to use external dongle when it has inbuilt SIM and 3G ?
