Oh yes, I tried to send a gmail today. It would only just sit there and say "sending" but never go through. I had to finally go to my desktop computer to send it.
I am also having issues after the latest patch. All the sync options are turned on. Not sure what is going on with it but very annoying to have to manually pull down my gmail.
Any of you guys have you contacts disappear after the update too? If so you've got something wrong in your sync. Double check both your gmail and your Droid. It's working perfectly on mine.
