JB IP4 noob question

Hey guy/girls,
I see that the tethered JB is out today! I originally used jailbreakme.com to do my first JB but then I had some warranty work done on my phone so I restored with iTunes and and then I upgraded it. As of right now I am sitting with IOS 4.2.1 (8C148) & a Modem Firmware baseband of 03.10.01. Will I be able to use this new JB that just came out or am I SOL?

Thanks for the help!

Thank you kind sir...I will do that tonight then!! Thanks again for the quick response!!

 

That doesn't really bother me too much....I need a certain couple of apps for a business trip i have coming it this will come in handy. As far as rebooting the phone....At least it will still be functional until I can get back to my laptop if I needed to reboot it....Most issues I believe would just require a respring though....
