Hi, I am in Australia, using unlocked Tour 9630 from Verizon USA
recently I start having random restarts, which i suspect due to bad battery because it doesn't restart when plugged to a power source, so I replaced the battery with non OEM battery (from ebay), unfortunately the restart still happen albeit less frequent.
I have read this forum and tried several things:
1. downgraded OS to .755 (using DM)
2. upgraded OS to .1078 (after wipe using BBSAK)
3. format the SD card
4. wedge the battery with a piece of business card paper
what I haven't tried:
1. install hybrid OS
2. buy a real OEM battery
Further observation, my Tour seems to restart more when I'm in my office and when the network/radio is turned on, when the network/radio is off, it doesn't seem to restart at all. I am not registered to office's BES and don't intend to.
any idea / suggestion would be very helpful

Thanks
