So far, the only devices to have Opera Mobile 9.5 for Windows Mobile are the HTC Touch Diamond and the upcoming HTC Touch Pro. The question for many has been when it would become available for other Windows Mobile devices. Opera has now posted some answers for us on their Opera Mobile blog.
As you probably know, releasing a version that works on a large variety of phones is more complex than making it work on one specific phone. You should also expect a few differences between the versions that are pre-installed on phones and the public version of Opera Mobile 9.5.
Opera Mobile 9.5 for Windows Mobile is now undergoing release testing and the first beta will be released on July 15th. There is no word yet on when the final version will be released though.
