Don't worry, the folks that provide the tool/software for jail breaking will have something. As long as you have access to the Internet you'll be fine.
Best wishes to you during your deployment. I'm a Viet Nam vet so I can relate.
2.0.10 is a baseband firmware which has nothing to do with jailbreaking. The only thing that matters in terms of jailbreaking is the iOS firmware which will either be 5.0/5.0.1/5.1
Of those, only 5.0/5.0.1 can be jailbroken currently
