Anyone Can Write A "Mobile For Beginners In Thailand"?:P

[Orgathai]

we get soo many mobile gadgets added, and so many applications, and so many providers:

I am sure that one of you has the knowledge to guide us trough a "Mobile for Dummies in Thailand"

Hardware :Smart phones, tablets, laptops , egde usb

Operating systems:1,2,3.....

Software: applications, GPS, etc...

websites : FourSquare, Facebook, Thaivisa

providers and their different ways to connect (in Bangkok, outside Bangkok)

how to connect your mobile gadget if you come to Thailand as a tourist?(Roaming??)

many questions, but I am sure there is a wizard on Thaivisa.com who can make things clear

( and we know it changes all the time, but if we have one post , we can add addenda, so it will be easy to find)

Thanks
