After 10 weeks of being available on the App Store, hit iOS email app Mailbox is dropping its waiting list that has encumbered many users. Now Dropbox-owned, Mailbox has added servers to handle the load, opening it up for all email addicts. 
Users can now launch the app and signup instantly, without having to wait in line that reached up-wards of one million people at one point. Mailbox would slowly let users in as the servers could handle the load. It was a seemingly good way for Mailbox to scale its service and build hype. 
Mailbox hasn't gone into specifics on how many people are now using the app, but did say it is delivering a whopping 100 million messages per day (and growing). "We believe we can now confidently handle new users as they sign up, so we’ve pulled down the reservation system," Mailbox wrote on its blog.
We're big fans of the application, as are many of our readers. In late-March, Mailbox grabbed the attention of Dropbox, who acquired it for a rumoured $100 million. Both teams have made it clear Mailbox will continue as a "stand-alone app." 
Dropbox must be helping with extra server capacity for the hoards of users. Now that it's available on the App Store for all, you may want to give it a try.
