Here's my dilemma. My LG Optimus has pretty much bitten the dust. My roomate just gave me a another one that I'm planning on dropping my SIM card under my carrier. I was planning on rooting my original phone, but was wondering if there would be any issues if I were to do that, THEN swap SIM cards to the SAME phone? Is it a different ordeal overall? Considering both phones are identical? Please Respond!
