Hard to believe when the iPhone was first released there was no way to send a photo or video using MMS. Now besides the ability to send these types of files, iMessage has expanded the capabilities of iOS devices to communicate. One jailbreak tweak named Doodle Message seeks to expand the capabilities of several messaging apps even further.
With Doodle Message, an MMS or iMessage composition gets the option to draw directly on the screen. Not only can you create a doodle from scratch and send your masterpiece to friends and family, but the tweak makes it possible to draw on a new or existing photo. This can be a neat way to highlight part of the image or write something fun directly on the image.
Doodle Message is compatible with several messaging apps besides the stock iOS Messages app. WhatsApp, Facebook Messenger and biteSMS are all supported. There are no settings to configure once the tweak is installed from Cydia. Doodle Message will add the option to Doodle right from the photo selection menu in Messages, or in similar places on other apps. The pen color and width can be fully customized to achieve the desired look.
Doodle Message is available on Cydia from the BigBoss repo free of charge. Check here for instructions on how to jailbreak iOS 6.x with evasi0n. You can also find out how to purchase and install Cydia tweaks with this guide.
