While I’m sure the majority of you are using Gmail, I’m betting there’s still a large number of users out there holding onto that old Yahoo! Mail account for contests, newsletters, special offers, etc. Even if you are using Yahoo! Mail as your main account, we won’t judge — but we will tell you about today’s update.

[Update: it appears a large number of Android users were getting errors when trying to download MC4 from the Play store. Gameloft has since pulled MC4 from the Play store until a fix is in place.]

Twitter has unveiled Instagram-like photo filters for its official mobile apps on Android and iOS. It’s been rumored that Twitter would roll out this feature by the end of the year, and the time has come.

You can choose from 8 basic filters and crop/enhance your pics before sharing them in the Twitter app. This addition comes after Instagram recently shut off photo previews for links shared in Twitter.

Same Instagram, fresh coat of paint.

A big Instagram update is now available for Android and iOS devices. The camera interface of the app has been improved with a quick preview of the last picture you took on your device. Now there’s an optional grid guide for taking pictures and a permanent grid to help you with aligning when you’re scaling and cropping. For iPhone 5 users, Instagram has included an “improved Camera Roll image selector for quick access to your last photograph.”

Today’s update also includes a number of speed enhancements, Foursquare buttons, several design tweaks, and a new filter called “Willow.”
