Can't make sense of these 3G plans from Docomo

[hotshot05]

I took a new connection of Docomo.
Was looking at their 3G GSM plans - http://www.tatadocomo.com/3g-prepay-packs.aspx [Circle - Karnataka(Bangalore)]


The Rs.90 pack(red box) says 300MB + 300MB but they do not say anywhere what is the meaning of it. Is it 300MB 3G + 300MB 2G or something else?
Above(blue box), Rs.93 plan clearly states that 600MB is for 3G data and rest 300MB is for listening to songs on Saavn.
Does anyone here know what these plans mean?

90 RC- 300+300 is a limited period offer.
93 RC- 600MB data is an Regular offer.

300Mb extra is for 3G i.e you will get 600MB 3G data for 90rs.

As @swatkats mentioned, the ones on the second with the * are currently having the additional (2x) data benefits at same rate. Would suggest to opt for what suits you.

As for the Saavn data - I think it will be similar to seperate data package, and you should get faster speeds from saavn.

Thanks guys.
Since I had been using Aircel for the past 2 years, I thought it is like what Aircel is doing presently - coupling some 2G data along with the 3G packs.
