I have had one for months. Only issues are battery life and headphones.
Also, one issue all these phones have, in certain data modes when 3g4g isn’t available, your phone doesn’t ring. Caller goes direct to voicemail when you are actively using the net when they call.
No one told me, I was missing a lot of phone calls.
And, as the Sidekick users found out, if the “cloud” goes down, you’re hosed.
