Twitter for Android gets push notifications and multiple accounts
Twitter for Android has a new update which brings some sorely needed new features: multiple account support and push notifications. Now, you can easily switch between multiple accounts in case you're a power user. But, the big news for more casual users is push notifications.
What you'll need to do is go into settings, then tap on the account name that you want to deal with. Turn on "automatic refresh" if you want push notifications, then choose which content you want notifications for.
The update is available now in the Android Market, and is free.
