Worked fine with my T410. I already had Astro file manager installed so skipped downloading that, just hooked the tablet to my PC transfered over the G Tablet.zip
to my sd card, navigated there with the Astro file manager extracted the files..navigated to the G Tablet directory which was created after the extraction, navigated to the app directory where I found the four apk files that are to be installed, I installed all four, did not open that last one as directed, powered off, powered on. Did get the prompt "Complete Action Using"..and I checked "Use by default" and "Launcher" and that was it..found the market app lauched it.. I already had a google account..it lauched the market and i downloded a game and it worked fine...I'm not sure how out of date the market is but I'll tackle that next..
Just wanted to thank the original poster for the help..great community here!
