Yes, I stood in line. My old phone was crunched - not dead, but it would have cost more to buy a replacement screen than to simply upgrade/replace it.

Bugs/issues

• Battery life is definitely much worse. Received wisdom is that this is due to the 3G radio… Turning off 3G to save battery life really isn’t practical without something like a single button toggle app — any takers?
• The new device won’t take a charge from the little Belkin Griffin adapter that I have in the car. Apparently this is a known issue. Luckily, this adapter is in two parts, the plug that goes into the 12V “lighter” socket, and a USB-iPhone cable that plugs into that.  It turns out that while the Griffin “USB” cable doesn’t work with the new phone, if I replace that cable with the USB cable from the iPhone power adapter, it works fine.
• Apps take a long time to load in general. A friend of mine who works for Apple says that the SMS and Contacts apps in particular can slow down when you have a lot of SMS messages (or Contacts). If you have a Mac, you can backup and clean out old SMS threads with SyPhone, but I’m not aware of an equivalent for Windows.
• Contact list right-hand alphabet index scrollbar takes 5-10 seconds to start responding after contact app is loaded. I can understand that it takes a while to pull 1000-2000 contacts into memory, but still, ugh! Apple can do better.
• Contact search input field should float as you scroll so it’s always visible.
• There should be a preference to always allow Camera and Maps to use GPS location services, instead of prompting me all the time.

Good stuff

• Appigo’s Todo app with built-in support for over-the-air sync with RTM. It’s not “push”/real-time sync, but the app is very well done, and the sync works well.
• Pandora - free! rocking!
• Tuner - streaming internet radio stations! Check out WSUM, WFMU, KALX, Little Radio…
• Pandora & Tuner streaming over 3G, jacked into the car stereo!
• Movies.app
• Remote

Missing stuff

• KeePass/KeePassX password manager. I switched from SplashID to KeePass a while back because KeePass has a much better UI, and also because SplashID has Windows & Linux versions that use the same database… I don’t really need the Linux feature, so I could switch back to SplashID, which does have an iPhone version ($9.99 in the App Store). I took another quick look at SplashID though, and the UI kindof bites, and I bet KeePass will come out on the iPhone before too long.
• Notepad sync - so lame that this still doesn’t exist
• Google Calendar sync. I was using NemusSync on my 2G phone, but an equivalent doesn’t yet exist for the 3G. A native Google sync app would be better.
• Google Contacts sync. Something like Funambol might eventually work, but a native Google sync app would be better.
• 1Shoot - best little one-function app ever!
• uPoze - automatic Flickr uploading - I want this back!
• jailbreak, of course - not quite out yet, but almost…

I’ll update this post as I learn more
