Mobile Broadband in India
Not that it'd be really neccessary given the availability of internet cafes in India, but for the addicts or those like me that need to work using their own laptop, Reliance currently have a special deal for Mobile Broadband. The postpaid option will be difficult without address in Inida, but they have a prepaid option too.
For RS 3500 you get a USB modem and 10 GB worth of bandwidth valid 30 days from activation. Some 35 cities have high speed access (e.g. Delhi, Lucknow, Mumbai, etc), but you get slower yet decent enough speed out in the woods too (comparable to most net cafes).
