Iphone stuck in recovery mode

*Iphone 4

*stuck in revovery mode

*Tried to restore multiple times through iTunes to no avail.

*did not do anything to provoke recovery mode, I wasn't updating my phone or even using it, it was just one my bedside table I woke up it looked as it had died when I plugged it into my charger it came up with the connect to itunes screen and wouldn't let me do anything else. I find it worrying that it just spontaneously decided to go into recovery mode it has never done this before and is a relatively new refurbished product.

*I'm skeptical of TinyUmbrella and such as they always seems to destroy my computer but any legitimate help would be appreciated

Thank You
