I must be going deaf! I never put my phone in my bag, I always have it in my coat pocket or trousers pocket so I can hear it when it rings. Honestly, the bags are relatively heavy so I try not to buy too many accessories to weigh it down. It's a personal choice, if you like it, go for it, but not for me. And yeah, Lilach is right about the phones being a different size each time there is a new release, just look at ipods. I think all the 3rd party makers for ipods have about given up as the size changes every year!
