Was running CM7 nightlies for a while but most recently was running CM7 stable (7.1.0.1-NS I think).
Wondering whether others are seeing anything similar.
1. Phone and SMS works.
2. WiFi works but seems to be slow. Browser and other apps take a long time to download anything, e.g. GMail takes ~5 seconds to show first view; Google Reader can take 10s or more to update feeds; browser is very laggy.
3. Carrier data doesn't work. The signal bars seem to go blue (i.e. on) when WiFi is connected, but if I disconnect WiFi then the carrier bars also disconnect. It also seems to flip between E and 3G a lot, like it's thrashing.
4. Overall phone UI is extremely laggy. Very slow compared to CM7 stable. Apps can take multiple seconds to open, apps drawer takes seconds to open, nothing scrolls smoothly.
5. Battery usage is poor. Runs down battery in 8 hours or less with moderate usage. Device seems to be much warmer than when running CM7.
6. Wallet crashes. I initially got constant messages about "Unfortunately wallet has stopped". Doing Manage Apps > Wallet > Force Stop seems to help.
7. Up-to-date Market app doesn't work. It opens and I can search for apps but when I click on a specific app it crashes ("Unfortunately Market has stopped"). If I Manage Apps > Market > Uninstall Updates then it works.
