Hi, I have Sony Ericsson X10 smart device, which I want to use for apps and surfing, and I have a Sony Ericsson W715 with a data plan which has the battery life I need for voice calls. I want to have the X10 make use of the W715's data connection, reverse tethering via bluetooth. I've played with android tablets in stores and can achieve this so easily, the android tablet just connects BT and uses by W715 data connection very sweetly. Perfect. Surely I should be able to add the app which does this on the andoid tablet, to my android X10. It's all android? But I can't find anything. Any search for tether goes the other way round, reverse tether searches all lead to USB cables. Has anyone achieved this?
