Synble is a little app that backs up your phones SMSs and call records onto the net.
It also has the ability to push content from the web onto your phone. You can get your twitter @replies and DMs delivered to your SMS inbox in real time as well as RSS feeds from your favourite websites. You cant reply to twitter messages from your inbox however.
The real appeal of this app is that backup feature, if you’ve left your phone at home, you’ll have access to your missed calls and texts from any PC!
