That's exactly what I'm going to do, Viking! Good call, buddy. I'm going to compose a step-by-step guide of exactly how I did it (installed Market, that is...), written for (and by!) total beginners who are completely new to Arnova 10 G2. Hopefully, the post will be made 'sticky'...
Briefly, I didnt use Arctools. I did download it, and I tried several times/ways, including rebooting, but it just wouldn't work. So I downloaded the zip file, unzipped it, then installed each file in the correct order, quick reboot, and hey presto - I now have Market and the GMail app on my tablet. Happy days!
The only issue I had was the Unzip app I had kept closing when I tried to open the folder with the zip file in, but it didn't crash with other folders I opened. Strange, I know, so I just moved the zip file to another place, and it worked fine.
So, gimme a couple of hours and I'll have the guide up and posted....
Til then, and thanks again y'all!
