IBM is ready to ship an Android-compatible new version of its push-based e-mail software Lotus Notes Traveler, an IBM employee wrote in a blog posting Tuesday."Today, IBM is shipping Lotus Notes Traveler 8.5.2.1. New in this release -- the Notes Traveler client for Android OS," wrote Ed Brill, IBM's director of product management for Lotus software, in a blog post Tuesday.The new client gives access to e-mail, calendar and contacts on any Android version 2.x-based smartphone or tablet, Brill wrote.There is however one problem: It can't be installed on Android-based devices from AT&T, due to the fact that AT&T only allows applications to be installed from the Android Marketplace. But the operator has indicated it will have a solution available in early next year, according to Brill.
