Wen you mess up some rom, in the end, you have to sign it...Means it carries your signature...so unless you are s-off, you cannot just flash a custom rom...n also i don't think you can cheat the device just by editing the version...I'm not quite sure about the answer...
I had that idea last night but didn't know how to do it. I can try it if someone provides me with the instructions on doing so. I would LOVE to get rid of the stupid 2.43 rom on my phone.
