One thing.
There *IS* an issue with the GPS on some OV phones with IHO. I've been struggling with it ever since I got my phone late last year. Using it in some circumstances will cause the phone to reboot. This has nothing to do with a botched install, configuration or apps installed. I've used Backside, Mirage (which is my goto), a few of the others with the same results. Overclocked or underclocked. Moving or standing still. Using Google Maps or another GPS app. It is a known issue, and no amount of reinstalling is going to help crickie. I've installed IHO on my phone probably 15 or 20 different times, many of them completely fresh installs, and it has never made a difference.
It doesn't happen, btw, with the stock firmware, but I use IHO because the benefits far outweigh this one issue for me.
The only thing that I know has any bearing on it is that it seems to happen mostly when there's an iffy data connection, either wifi or 3G. For instance, i can sit in my living room with the GPS running forever with no issues. If I move to my back room, where the wifi barely reaches, it will usually kernel panic within 15 minutes or so, predictably. Same thing if I'm driving around the rurals where the 3G drops in and out a lot.
Anyway, I appreciate that the stock answer and assumption is a botched install (i've had weridness from that too), but in this case, there is an actual known problem that is very very difficult to track down, and seems to be tied to a particular revision of phone in a particular circumstance.
