I'm about to buy my first Android phone. I've decided on the Samsaung T-Mobile Vibrant mainly because I need a phone that will work internationally, both in America and in India. I can buy it at a local T-Mobile store in Palo Alto for $199 or I can buy it for $99 over the internet from letstalk.com. Does anyone know if it's safe to buy over the internet? Are there any reasons not to?
