Why does my iPad reboot itself, Why does my iPad reboot itself

Question

My iPad tends to reboot itself for no apparent reason.
For example i was on Skype talking to a friend and it just rebooted itself.

Answer 1

I have iPad 3g+wifi 64 gb with and it's 2 years more old.
once a while it's fine, until suddenly there are "no simcard" issues after sleeping at night.
After that problem, i never had any signal using "any" simcard. also, after inserting simcard into my iPad, suddenly my ipad had this restart problem. so.. i were trying :
1. reset network --- > still have a problem.
2. restore on itunes ---> still have this problem though
3. reset all settings ---> this one is good though, if you were reset all settings and you can see progress bar completing until the bar is full then next time it's finish reset, i can guarentee that my ipad will goes to "normal" even until now i only can use wifi only.  if you already tried reset all settings didnt change reboot suddenly behaviour, then you must try reset all settings all the time until you let it ipad without activating it for at least 10 minutes.
for apple inc.
i hope you can fix this problem either it's hardware or software problem. mine is out of warranty but you need to handle this carefully, and don't let apple people say "I NEVER SEE THIS PROBLEM BEFORE" because you already had this communities and you sell product expensive as we bought it expensive as you sold. i have no intentions using genius bar if the solutions is only "REPLACE" but i have to pay another 4xx USD for a change because my iPad is no warranty. fix the problem or your customers go away. apple also has many issues right now including suddenly apps closing. hope apple inc willing to do their bests just like before. again.
regards.
