i recently bought a white iPhone 4 32GB off ebay. it's locked to a different carrier running 4.1 i'm wondering if there is anyway that i could check if its been jailbroken before so possibly downgrade?

A WHITE iPhone 4? Is this a custom built phone? First thing I'd do is go into Settings, General, About and see what modem firmware you are at.
 
Well.... "a White iPhone" of ebay already sound VERY fishy but to answer your question there is not really any way to know for "sure", you can check for the SHSHs and see if cydia have them for that phone but that doesn't mean it was JB.
 
You can JB it now on 4.1
Even if it was JB before and it has SHSH's on cydia you will not be able to unlock it if its on official 4.1 firmware with modem firmware version 02.10.04
Cant downgrade the baseband, just the firmware.

Essentially this. If your modem firmware is 1.59.00 then you can jailbreak 4.1 and then unlock using ultrasn0w and you should be all set. :)
