What is the best Windows program for tweaking my mobile phone, particularly the internet download speed. Or do I have to hack it?
One way would be to use use a mobile web browser like Opera (with Turbo switched on) that uses special compression technology to deliver web pages. I don't know if there are any freewares for this, but there is a shareware ($7) called NetworkAcc. I haven't tried it, so do read up more on it if and before you decide to go for it. If you find a freeware solution, do let us know about it.
