At this point I am considering getting a tablet that I can install Linux on (with an up-to-date kernel for fucks sake) and just getting a cheap burner phone. I rarely call people anymore. Mostly I use my phone very similarly as to how I would a laptop. However, a laptop doesn't fit in my pocket.
I dont know how the G5 works but my wifes G4 was a total pain to get set up with custom rom and recovery.
