I'm building a prototype of a service that will let you test your mobile site or app on real mobile network - i.e. you will be able to see how your app will perform on various mobile networks in London/UK or New York/US. Please let me know if you'd be interested in testing it, have feature ideas/requests or have seen something similar out there. If you're interested in talking - shout out on twitter - @3marcin or email me on grodzicki on gmail.
