So it looks like I'm getting a Blackberry for work, which is good and bad news. The good news is that I'll have two phones, so I can use my work phone for calls, and I have Google Voice. The bad news is that I would have to carry around two phones. I'm thinking about unlocking my Android phone so that I can pop my work SIM card into it when I want to use it for work. I have Touchdown loaded on it, so I can pretty much do everything with it that I can with a Blackberry. I can see a few potential problems though: 1) What if someone wants to get in touch with me using Blackberry IM? 2) I would have to swap SIM cards in and out if I wanted to switch between T-Mobile (personal) and AT&T (work)... I could totally see myself dropping a SIM card or breaking one or something. Are there any solutions to either of these issues? Concerning #2, I was wondering if there was possibly a way of having one SIM card in the phone, but being able to switch it back and forth (like flashing the data from a different SIM onto it or something) so that I wouldn't have to keep swapping SIMs.
