did you save SHSH blogs for 4.2.1. if not you can't upgrade to 4.2.1 as the apple is no longer signing 4.2.1. It is now signing 4.3.

Install TinyU http://thefirmwareumbrella.blogspot.com/ and click the "Save SHSH" button and in the SAved SHSHs for iPhone window it will show the SHSHs that are saved from your phone.

If you mean can you use that to "beat the system" because it's running 4.2.1 now, no, you can't. It doesn't work that way. It's not about what firmware you're running, it's about what firmware Apple is signing. Only a time machine can beat that system if you didn't save 4.2.1 SHSH's when you had the chance.

No. You can download 4.2.1 all you want, but it won't install w/o 4.2.1 shsh's. Yes, you can go to 4.3 and jailbreak, but it's tethered.

OP, if it's old bootrom then you don't need shsh's, as a rough guide to determining that you'd need to post here the first 5 characters of the serial# only.
