Firmware 370. What do I do?

[corgi74]

Hi

Got one of the Funstock refurb unite yesterday and it's on firmware 370. I've already ordered a NGX jailbreak kit from Aliexpress but I don't know if it will work and I'd rather I jailbreak from 500 for the improved picture quality. 
What are my options please?  Is it good that I'm on 370? Will the jailbreak improve the picture quality?
Apologies for what might be silly questions but it's all new to me. 

Thanks

370 is just an older firmware version.

You should still be able to jailbreak straight to your desired jailbreak firmware version. I'm pretty sure that it doesn't matter which version you jailbreak from. The latest jailbreak versions are based off the v500a firmware so you'll still get the benefits from the v500a firmware version once you jailbreak, like improved picture and sound which the 370 firmware doesn't have.

That's brilliant. Many thanks. I was just concerned that I needed to update to 500a before I could jailbreak.
Wish my jailbreak kit woukd hurry up and arrive now!!!
