I bought my Droid in December of 2009 but due to some issues, I had to get a replacement one. I just got a replacement Droid yesterday and right away I noticed various differences. My phone case I used for my previous Droid did not fit on the new replacement Droid, the keyboard looked much more flat and did not seem to have the more bubbly buttons like my first Droid (I put the keyboards side by side), the SD card slot is white rather than black, and the sliding mechanism feels different. My biggest problem is that my case won't fit on my replacement Droid and I don't know what to do about it. Am I going crazy or did Motorola modify the Droid months after it was first released?
