Downloaded the 2.1 update and had similar issues with weather and meail. Got most of those resolved. One issue i have not been able to resolve is since the update I now have two "call log" apps and two "teeter" apps. i have not been able to find any way to remove the duplicate. Please help!
I do understand how annoying duplicate apps can be and whether not they are taking up double the space. If they they will not uninstall, even with an uninstaller from the market, try doing a factory reset. Let me know if any of these options work for you.
