Tethering apps will work with FroYo unless you uninstall them first. Then you'll have to reinstall them to get them to work. Funny how that happens, no?
By the way, random means random. That means random. Random, in case you are unaware, means without rhyme, reason, order, favorite locale, or penalties for bad haircuts. Yes, I'm talking to you. That 'do? Totally not you. But Verizon doesn't care, and your Droid doesn't care.
Speaking about not caring, your Droid doesn't care if you have a bad haircut, but it does care about what OS it's running. You don't want your favorite gadget to feel left out, do you? To feel like you don't love it anymore?
If you don't want your Droid to feel this way, try the patented FurBearingMammal Manual Install (tm), as endorsed by <insert Mod's name here>. Simply follow the underlined link road above and when you're done, enjoy the FroYo goodness!
Limited time offer, expires at midnight or when the last OTA is installed, whichever comes last.
