in case you wont be able to fix it there's another solution. I also have the same problem as yours and the same phone as yours. My phone is not detected by eclipse. But my PC can detect the phone through usb drive and through Kies(sort of like itunes for android). The altenative solution to test your program on your phone is to locate the .apk file from your projects folder in eclipse. its in the \bin folder. then copy it into your sd card. Then on your phone, locate where you placed it and click, the phone would prompt if you want to install it. install it and it should work now.(delete if you want afterwards). IF you happen to solve the issue with our phone not being detected by eclipse, pls do email me: kobe.ed6@gmail.com . Thanks and i hope i was able to help,atleast. :D
