Friday night, naturally before the long weekend (at least here in the states), the rooted LG (F3 on Virgin Mobile) starts acting up, with the phone process crashing. After a couple of reboots I update the PRL and profile and it's then working fine...for a little while. Same thing happens again, when I try to restart it freezes early in the boot process, nothing happening except the the power button led cycling through the colors. No change in subsequent reboots and no time to deal with it, but Saturday night I'm able to play with it a little. I find that if I remove the SIM card, it will come up fine, though with obviously limited functionality. SIM installed= frozen boot, each time, SIM removed= boots fine, each time. (We can now all shake our heads and cluck our tongues about the complete lack of meaningful support one ever gets from VM...haha). With that bit of detective work, my conclusion is that the SIM must have flaked, so that's when I discover there's no store into which I can walk and buy a new SIM, I have to order it. I'm not worried about dropping a few dollars on a SIM, but having to wait yet a few more days is irritating, so I'm just floating the idea to make sure I'm not chasing a red herring. Waiting several more days to find there's a deeper issue that could trigger me having to buy another phone isn't my path of choice right now, largely due to the delay(neither is just buying a new phone). So for those of you more knowledgeable than me on SIM-enabled Android devices, I'm just seeking confirmation that the odds are overwhelming that replacing the SIM is the solution. My humble thanks for any insight you may have.
