I'm afraid that I cannot provide any specific suggestions, but you're welcome to look over the list of phones which support the Mobile Authenticator application by visiting
http://mobile.blizzard.com. Also, your fellow players may be able to provide some suggestions based upon their past experiences. :)
Our Web and Mobile developers are trying to develop the Mobile Authenticator application for as many phones as possible, but I do not have any information to provide in regards to specific phone models. You may simply want to check back on the aforementioned site for the latest list of supported devices.
Also, please keep in mind that you can purchase the keychain version of the Authenticator at the Blizzard Store for only $6.50.
