Despite the Motorola Droid and HTC Droid Eris being on the sales floor for just under a week, it appears that Verizon is preparing a software update for each. The OTA revision, which is rumored to hit on December 11th, is said to correct a number of known software issues with the two devices. I have to give credit to Verizon - instead of letting the issues spread, they're taking proactive steps to fix the reported problems.
