Can someone take a look at what I have & let me know if I need to do anything at this point to ensure a future JB?

Thanks!

Iphone 3GS #1
3.01 FW JB with Redsn0w
ECID on file with Cydia.
I did the USB dump and got the files from purplera1n.com prior to the 3.0 jailbreak being released for 3GS. I have a file with files named "Controller, and purplera1n.log".

Iphone 3GS #2
3.0 FW JB with Redsn0w.
No files saved since by the time I bought the second phone a JB had been released and I didn't need them to JB 3.0
No files saved on Saurik's server with Cydia. The wiindow had closed before I could explain to my partner how to save them.

Neither phone has been upgraded to 3.1 and I am not needing to restore. I would like to keep my baseband for future resale value though, so waiting for a custom FW is not a problem. I just want to make sure I don't need to do anything right now to JB any future FW >3.0.

Thanks!
