So I'm thinking of getting one of these in order to boost the (very poor) 3G signal my 02 mobile broadband dongle currently gets. Has anyone ever used one of these before? If so, any comments? One of my main wishes is to get some form of reliable upload ability - at present the connection is too unstable for any uploads of more than a few hundred kb. I get downloads of 50 - 100 kb/s, and on a good day a ping of 200ms (although it often spikes, causing me to get auto-kicked from MP games). Any feedback would be appreciated
