I currently have an 8830 WE from Sprint, I just noticed that there is a SIM card in it. This is actually my 2nd 8830 WE from Sprint. I warrantied out the first one due to the screen constantly going all white and not being able to do anything on it.

I don't recall seeing a SIM card in my original 8830 WE. I'm pretty sure I would have noticed it as this SIM card is white and I pull the battery once a day for maintenance and I have inserted and removed my micro SD card numerous times (on both the new and old phones). Every time I power up my phone, it says that it detects a SIM card and asks if I want to automatically detect whether to use GSM or CDMA based on network availability.

So my question is, have the 8830 WE from Sprint always had SIM cards? or is this something new that they have started? I have tried removing it and my phone does not start up so I am assuming I need to leave it in...
