The iPhone can do lots of things really well. However, sending pictures is not one of them. Social networking company JuiceCaster has developed an app that will help out the Big Apple.

JuiceCaster’s Flutter is free and available on the Apple App Store. Flutter lets iPhone users send picture messages and optional geo-tag location data to virtually any mobile phone number.

With the Flutter application, users can send a virtual MMS to one or more phone numbers in the iPhone contact book. iPhone 3G users can automatically geo-tag both pictures and simple text messages so recipients get a link to view the picture, with the sender’s location pinpointed on Google Maps. Flutter transmits picture messages over Wi-Fi or via a user’s existing carrier data plan. 

Last month, JuiceCaster’s mobile social media service was made available for the BlackBerry Curve via a free beta application for AT&T and Verizon Wireless customers.
