I have had this problem for maybe a few months and it is starting to really annoy me.
When performing seemingly intensive things (for a phone) such as recording video and running the Maps software, it will all of a sudden restart itself and fail to reboot.
I have to leave the battery out for about 5 mins and put it back in for it to work again.
Ive tried 2 batteries and it still happens. Could both batteries be fubared? Could it be the memory card I have in? It is a 6GB sandisk.
Thanks
