I AM SUFFERING a HUGE problem with this phone. The phone is great, it is definetely eye-catching, fun, innovating, etc.

Everything was going well, until once after connecting it to my PC using the provided USB cable and then unplugging it, the phone just went nuts, and it goes on this endless loop where it restarts over and over again, until I press the restart button with a toothpick or something. But as soon as I hit the power key, it goes at it again.
I was told that it was probably my memory card, so I removed it and it started working again as usual, however after I connected the phone to another computer to upload some files to it, it continued doing the same thing soon as I disconnected it, and this time without the memory card being inside at all!


I am very frustrated because my phone is completely useless at this point, I would forever be thankful to receive information on how to fix this. thanks in advance.
