Palringo‘s a bit of a newcomer to the game, but has a few promising features, like sending audio, pictures and text messages over a variety of different platforms. The voice notes system was a bit of a downer though, since it just sent a link to a mobile web site to the recipient rather than a direct file transfer. Palringo also requires you to sign up for an account with them, which is a bit counterintuitive – the reason folks get a single app for all the chat platforms is because they’ve already signed up for too much stuff. On top of that, the menu system seems heavily geared for standard feature phones and not really optimized for BlackBerry just yet.
There were a lot of hooks that got me immediately interested in Instango, namely cheap SMS messages and voice calls through their client. Another especially cool feature is being able to add RSS feeds as contacts, allowing you to get updates in the same spot. At WES I saw Doug getting twitter updates in GTalk in a similar way, and thought it was especially cool being able to get both RSS and instant messaging utilities without having to switch apps. While the conversation tabs make for quick switching, for some reason entering text in them opens up a new window rather than simply having a text box at the bottom, which jars the flow a bit.
