IPhone 4's standard "notes" app doesn't save new updates?

Question

I regularly use the 'notes' app that comes standard on the iPhone for everything. Shopping lists, to do lists, you name it. But with the new iPhone 4, the app doesn't save new edits. I'll type in or delete something, and then after I hit done, the "thinking" thing at the top left rolls around a few times, and then whatever I just typed in disappeared, or whatever I deleted reappears. Help!

I don't live in that area (I'm in northern Orange County, CA), but my neighbor and I have been having the same problem since last Saturday (Feb. 5) in the area around where we live (we both have iPhone 4's, and they still work fine in other areas). Note that we have full bars, and the "3G" symbol on the display, but get no data over 3G; disabling 3G allows access using EDGE (slowly), and phone/texting works fine (it's just the 3G data in our neighborhood that's broken). Since we both have WiFi in our homes, we didn't initially identify the 3G problem; what we both noticed was a sudden increase in iPhone power consumption (beginning last Saturday) when we are in our neighborhood (even when the phones are idle); I used to go 3-4 days on a charge, but now the battery drops at a rate of about 10%/hour when I'm around the house. Interestingly, my neighbor also has an iPad, and it doesn't exhibit the problem. Both phones and the iPad are running iOS V4.2.1. We've tried all the normal things (rebooting, clearing network settings, etc.), and nothing works. I spent some time on the phone last night with AT&T, and they are going to send someone out to check connectivity.
