It's jailbroken so I can't just update the firmware through iTunes, I'm not quite sure what to do.
Apparently you update the firmware and then just jailbreak it again, but that seems risky - i'm sure there must be a way to just update with cracked versions of the official firmware.
Your carrier will always support the firmware - as long as it has the supported baseband then the firmware won't matter. I know people who haven't ever updated to even the 2.0 software (mainly because it works so they're happy) and they work fine. Nah - the thing with jailbreaking and the iPhone is you don't update unless you absolutely have to. If it works then by all means do not touch it.
I know I'll be updating to 4.0 when it comes, although if it's anything like 3.x problems then maybe not. Usually with jailbroken devices, you need to restore to a clean firmware and then update to the new firmware manually in iTunes (hold Shit and click Restore) then jailbreak again with redsn0w or QuickPwn (at least that's my experience of restoring and re-JBing in the past).
What have you got installed besides official Apple and App Store apps?
