While iPhone, BlackBerry, Android, and Windows Mobile users have been able to browse the internet with ease this weekend, Sidekick users haven't been so fortunate.  Due to a server failure at Danger headquarters on Thursday evening, Sidekick users across the nation have been unable to perform tasks that pass through the servers - including e-mail, IM, internet browsing, and the contact list.  Texting and calling are unaffected, but as with any outage, users are quite frustrated.

T-Mobile promised that the service would be up and running yesterday evening, but as of this afternoon, the servers are still down.  Sidekick users, I'm sure you're frustrated - are you going to call in and demand a refund for the downtime?  Submit your frustrated comments here!
