I'm sure it's been asked before, but what would be the benefit of upgrade it to 2.1 for my 2G phone? Is battery life increased? less crash? So far, I heard people saying 2.1 does nothing for 2G phone. Additional Question, I have 2.0.1. Can I just restore to 2.1 (using itunes 8) and winpwn it just like what I did with 2.0.1? Thanks guys.
