Not sure about this little pre release party. Reading the engadget reports, a lot of users aren't finding voice memo or file management and some are. Sounds a little fishy to me. I can wait another day to make sure I get what my phone is supposed to have...
Isn't general consensus now that you should always do a restore from iTunes with a hacked phone before updating? Seems like a worthwhile five minute investment to prevent a nice black and silver brick!
Just finished upgrading (if you want to call it that) to 1.1.2. My phone was modded before, but I first restored back to 1.1.1. I then did the upgrade to 1.1.2. The only real change I've seen is the little icon in iTunes that shows the battery charge. I don't see anything new on the iPhone itself.
I've been running this since last night and I really see no changes in this. The battery status icon someone else mentioned is an iTunes feature and not due to this update on the iPhone, my Classic iPod shows that same battery icon when it's connected to iTunes.
