For those who don't want to wait for the newest update, you can manually update here. Do a backup of your items as a precaution but the update should not erase anything, its just a patch...
Update includes Silent call Bug Fix
http://www.megaupload.com/?d=ZHNS1RUMIf you’re running a custom ROM or are on a rooted device, you’ll have to wait for your respective developers to integrate this update into their modifications (unless you want to flash to stock and then update).
1. Download the file above and rename it update.zip
2. Place this file on your SD card (
DO NOT place the zip file in any folder on the card) then shut off your phone
3. Hold down Volume Down and Power to enter the bootloader
4. Select Recovery and press the power button
5. The phone should reboot and give you a screen with an exclamation point
6. Hold down Volume Up and press the power button (this is in contrast to the old one where you held the home button and pressed the power button... I guess this is new from the 1.5 to 2.1 update)
7. Select Apply sdcard:update.zip
8. Wait about 10 minutes for it to finish its thing, it should verify and patch system files, lots of yellow text...
