We have been able to implement a version of YorkieTalk specifically for iPhones and other mobile devices, such as iPod Touch, Blackberry, and Android phones.
We have not checked each and every feature of the mobile YorkieTalk, so if you find any bugs or issues, please let us know and we will look into it.
YorkieTalk.com Forums - Yorkshire Terrier Community
The first time you use it, you may need to change your default style on your mobile device from YorkieTalk.com Style to Mobile YorkieTalk, in the drop down box near the bottom of the page.
Just go to the main forums directory of YorkieTalk from your mobile browser and you will find a mobile version of YorkieTalk! Feel free to add the link as a bookmark, or if you have an iPhone, go to the forums link, then click the + button, select "Add to Home Screen" and you can add YorkieTalk as an icon on your iPhone page. You may want to edit the name to "YorkieTalk" so it fits better on your home screen.
(If you go to YorkieTalk.com from your phone, click on "Yorkshire Terrier community" or "Message Board" to enter the YT forums.)
