Hi,
Are you sure that new lot of Netsetter Usb Modems are 3G/UMTS enabled? Because current version available in Pune is upto Class 12 Edge (around 236 Kbps). A 3G/UMTS version could theoritically go to 384 Kbps, a difference of almost around 144 Kbps.
I enquired with Idea Gallery in Aundh, Pune and showed a guy there this thread. This guy talked to someone concerned on phone about new Netsetter stock, and even shared this thread URL but at the end told me that Netsetter being 3G is not possible, else they (Idea shop) would have got the information. As for the Idea network in Mumbai being 3G, are you sure about it? I guess the auction for 3G spectrum was to happen sometimes in Jan/Feb 2009.
If you or anyone in Mumbai has the specs of this 3G Netsetter, can you post a picture of the modem package box here that mentions the technical details about the modem. Apart from that additional information about which Idea shop/gallery in Mumbai is having this stock (their contact address/number) so that I can get the local Idea guys to interact with them and find out how to get 3G Netsetter new stock.
Looking forward to your response.
Regards
Sandeep
