The Republic Wireless Defy XT should be getting a software update this evening, and it will address the two biggest issues with the phone. I've been giving the service a run to see how it compares, and the two big drawbacks seem to be sound quality, and not being able to send a text while on Wifi. Both these issues are said to be fixed with this update, as well as Wifi enhancements and bug fixes.
The OTA is slated to begin rolling out at 6PM ET, and Republic says you'll need to be on Wifi with 50-percent or higher battery power still available to get it.
While Republic is more about disrupting the current telecommunications mess the US is in with low priced service than they are fancy cutting edge devices, it's nice to see them not let the little Defy languish away with bugs. If you're using the service, be sure to check for updates if you don't get a push notification.
