Remote desktop iPhone app vs BT Home Hub 2.0
I was about to buy that app, but I'm a long time user of LogMeIn Free were from here (Denmark) I help my mum and dad as well plenty of friends with their computer related problems back in my home country (Portugal)

LogMeIn Free was a fantastic as free solution, no hassle with proxies, routers or anything as it works with port 80 (http traffic).

So I bought the LogmeIn Ignition App and continue to use my access to all computers that i used before. It's a bit expensive ($29.99) but I bought it within a promotion discount and works marvelous and super fast!

I can now access any windows or mac computer from my iPhone or iPad with no worries.

It's just an idea.
