Native install is running Android 4.2.2 kernel 188.8.131.52, Quad Band, Dual SIM, MicroSD card slot, 140MB internal storage.
It seems to be a decent little device but has a number of extras installed (skype, a couple messengers, etc.) by default, and for some reason won't allow the install of OpenVPN Connect from the play store ("Your device isn't compatible with this version."), so I'm wondering if anyone has messed with one of these and gotten a clean build working (with play store of course).
For those interested (or looking for more details) go to the TMart site and search for it (I can't post links yet soo..) (FYI they took about 5 weeks to get here..it took some strange route..lol)
