I will be in India for a month and I have a jailbroken/unlocked iphone to use in India. I want advice reg. which is the best company that offers both phone and internet service (like 3G) in India? Usually how long does the process takes? How much will be per month? Can I wait to go there and get it or do I need my relatives to apply for me right now, so that it is ready for me when I arrive there?

Thanks all in advance.
