What are the best ways to connect an Arduino or a microcontroller (PIC...) to Internet/Web. I would like to be able to send and recieve information from the Arduino/PIC to the Web and vice-verse even if there is no WiFi around. Maybe connecting to my phone using Bluetooth and using it's internet data (3G) is a good idea? What I am trying to achieve is Google Search and response from the results using Arduino, everywhere. (Carrying my phone with the 3G around is not a problem since I don't think it's a good idea to connect to the radio cells around and probably illegally get information from the internet? Any suggestions will be helpful.

There are GSM shields for the Arduino, yes. But as far as using it as a hotspot for your phone, most likely not. I doubt you can connect your phone to the internet via the GSM shield because you'd essentially be stealing data from a network provider.

However, some of these shields have a SIM card slot so you can place your SIM card inside the device to connect to a network and you can essentially allow it to have the same functionality as your phone and you could make a hotspot that way. For instance, you can send text messages with the shield or you can connect to the internet with the shield.
