AIM, Beejive, IM+ updates
Three key instant messaging apps for the iPhone and iPod touch have been updated to take advantage of background push notification. AIM is now at v3.0.1, and relying on push technology can inform users of messages even when using another app. The update also enables notifications through SMS, implements fixes bugs, and lets users stay logged in for up to 24 hours. The paid version adds landscape modes for the buddy list and conversation views.
Aside from push notification, the multi-client BeejiveIM 3.0 now incorporates meta contacts, plus a variety of interface enhancements. Layout and color schemes have been improved, along with overall speed. Also multi-client, SHAPE's IM+ 3.0 has gained support for Skype Chat and Twitter. Messages sent through the latter can be set to use separate notifications, whether in terms of sound or vibration. Other improvements include favorites, a built-in web browser and a group for offline contacts.
IM+ currently costs $6, while BeejiveIM is $10 and the paid download of AIM is $3. Push features require the iPhone 3.0 firmware.
