Version history

What's New:
- General improvements and fixes for things that were working suspiciously well
- Fewer bugs. They didn't disappear — they just moved to a different carrier
- Slightly faster now. Roughly one signal bar's worth
Thanks for sticking around. Your 2004 phone would be
proud.
