Zingku is one of those SMS services where you can store and share photo’s from your phone to the web, set your web page to send you SMS reminders, gather a big crowd & their friends with txt messaging, IM, and email, all at once! (sounds like Swarmit), SMS poll with your friends, make mobile flyers where friends can get one by SMS’g a number, and RSS to SMS.
This last bit has got my interest, you can create what they call a mashup type of flyer by entering, for example, your blog feed, give a description about this flyer, and you will also see the flyer has a string of numbers (zingcode). Then people can SMS this number to fetch the latest entry or latest titles from your blog feed. eg text message libraryclips to: 12345 (this is only an example).
It would be good if they offered some sort of badge for your blog promoting the number to SMS, and to get some statistics.
Alternatively you can text the zingcode of your flyer to ZingkuPal to get it delivered to IM, so it is RSS to IM as well…similar to immedi.at
Other ways people can read your latest entry on their mobile phone is a mobile version of your blog feed at winkSITE, but people need a web enabled phone, even xFruits can generate a mobile feed for your blog, and lastly mobilize enables people to listen to your latest post on their phone by calling a number.
