On my BB they just see the one on the inside as I just swapped to a extended life battery on it a couple weeks ago because I was using it so much that I needed that extra life out of it when I wasn't near a charger. I'm not bothered by it. I'm more pissed at the store because I went there at 7:45 Friday night and they close at 8pm. They locked the doors as soon as we got out of our car and said they were closed and pointed to the clock that said 8pm on their wall. The store manager was looking at her watch and looking at the wall and said sorry we're closed. That really pissed me off.
I was able to get the 3 replacement phones off ebay for under $85 shipped anyhow so at least I'm covered there.
