Jailbreaking 4.2.10 on Verizon iPhone 4 PROBLEM!

Never heard of that issue, just restore and re-jailbreak.[/QUOTE

Thats exactly what I was trying to do but iTunes is forcing me to upgrade when I attempt to restore.

If you want to restore an old firmware you have to hold down shift when you hit restore to be able to select your own firmware. You will also need to have Tiny TSS server running to use your SHSH blobs.
