Now that I have CV (and love it), i would like to actually display one of the AT&T icons, just not the ugly white shopping cart. I have seen the CV icon for 4.6 and it looks much better then the white cage with wheels.
What seems odd to me, is the XMRadio icon changes randomly between the pre-4.6 boom-box, and the 4.6 XM logo. This tells me that the logos can change, I have no idea how though. I have done everything I can think of but the icons stay as shopping carts.
On a similar subject, kudos to Google for taking the time to update the icons for Google Sync, and Google Maps to match the 4.6 OS icons.
