Sony Ericsson Xperia Arc randomly reboots I realise this might be a repeat question, or discussed at length in some related posts, please don't hesitate to discipline me if I'm being redundant.

I just really want to know not only if anyone else is experiencing random reboots on their Xperia Arcs (or any similar phone), but also if they've successfully resolved the issue? This is driving me completely insane, and I'm really disappointed because I really love my phone!

I've done a hard-reset, deleted everything off the SD card, and updated the phone to the latest available software from Sony Ericsson (Android v2.3.4). I've installed only 1 application, the logcat application mentioned in this answer, but that was after my phone rebooted TWICE today, and I also have no idea what log information I'm looking for...

I've read this post by Zano, as well as this one by ninjaPixel with no avail.

I refuse to believe that 'jimmy-ing' in a piece of paper to make the battery make contact better is the solution - as the battery in my phone is pretty tight already, and I've witnessed my phone reboot while simply lying on the desk - but I've tried that too and will continue to monitor...

ANY help will be greatly appreciated, and I'll continue to research and post back any additional information I find. Thanks in advance!

UPDATE #1:

So far so good, no additional apps have been installed, and I've removed the logcat app that was on there as it wasn't helping assess anything. I've also installed a very professional piece of paper between the battery and the outside cover to help keep it more secure than usual. Holding thumbs..!

UPDATE #2:

Almost 2 weeks after my previous update, and still no reboot. It seems that although I wouldn't believe it to be as a result of the battery not connecting properly, it didn't mean that it wasn't the battery...I'll make this the last update, and say, in my case, the problem was because the battery wasn't connecting properly and adding a small piece of paper between the battery and the outside cover has done the trick. Thanks all for reading, and for your time and patience!
You need to update your phone to the latest firmware 4.0.2.A.0.62. I bet yours is 4.0.2.A.0.58

If you can't update the phone over OTA or PC Suite, use WOTAN to update the phone to 4.0.2.A.0.62. The reboot problem occurred on nearly all SE Xperia Models.
