Re: Lets keep this in perspective
"I fail to see why I should ever need to edit a hosts file on my phone."
Well there you see you showed your complete ignorance and also showed yourself to be a paid MS shill. Having used Linux O/Ss for at least the last 10-12 years the amount of editing I do with config files these days is almost down to zero and then only when I have some really daft beta type thing that want to test. You'll probably find you're editing DOC/XLS more often than O/S config files these days on LINUX!
While I don't like Google much and dislike Apple's mobile kit, I bought an SGS2 Android and like most of my IT experience I make sure I am careful not to put every single piece of my life into my tech, I "think before I blink" when it comes to personal info. Google are welcome to read my SMS messages and phone calls, if they think notes about train delays and "what's for dinner?" to the Missus are interesting! They're also very welcome to know that I am so boring I only like playing Sudoku games on my phone, they're very welcome to my scores.
So stop all the ignorant bollocks MS shill. Seriously you walk up to any punter on the high-street and ask them to name some mobile phones, £50 says they'll say something like, "Apple, iPhone, Samsung, Android, Blackberry", anything you hear will be a bonus an extremely rare. The high-street punters are driving the direction of the mobile market, makers of kit like MS no longer dictate where the market goes and that my friend is why the WinPho/WinCE whatever the heck it's called now, will simply be a footnote on the MS Wikipedia page within 6 months!
