I was excited for this, but had some real issues. Number one, it will overwrite Stericsson's lock screen (makes sense since we replace the framework-res.apk and services.jar). Secondly, each time I use this, even after a fresh wipe and install, gmail force closes (and yes, I have tried fix_permissions).
Empirical evidence can never establish mathematical existence - nor can the mathematician's demand for existence be dismissed by the physicist as useless rigor. Only a mathematical existence proof can ensure that the mathematical description of a physical phenomenon is meaningful.
