Hey all...wow, it feels good to be back! With all that's been going on, I took a bit of a break from Twitter/other projects to focus on school. But let me be the first to tell you that I'm so excited to get back to work and restart development on OldOS and a variety of projects.

Have found a way to circumvent this. I don’t particularly love the solution in the long term, but it’ll do the trick for now.

Quick update. Unfortunate the release of Mail has to be pushed back a few days (Max 5) as we wait for Google to verify our OAuth.

Here's a fun little experiment: an endless live stream of an iPhone 3GS. Talk about a nostalgia overload! It's up on zsk.dev/live.
