I haven’t been active on my YoWorld is quite some time. I don’t have internet for my laptop and can’t get my personal hotspot on my phone to connect. Is there any way to play through IPhone? Please help!!!

You can try setting the Browser on your phone to DESKTOP MODE, logging into Facebook, then https://apps.facebook.com/playyoworld/

Be aware that's a lot of detail for a relatively small screen.
Other players recommend using a stylus when playing this way.
(I'm using a HTML5 non touch Chrome Book so I have a moderate size screen.)

You won't have access to the new features on the new version such as the dance podiums, etc. but can do pretty much everything else.
Also be aware BVG doesn't officially support playing the Yoworld decorating game on a HTML5 mobile device.
(As opposed to the Yoworld Mobile Companion App).

What crushed said, could use tablet as well.
