So how did the new iPhone do over the weekend? According to this report (based on Piper Jaffray estimates), it sold 750K units. For context, the iPhone 3G apparently sold 1 million units during its first weekend. Here are some other estimates and figures from Piper Jaffray's in-store survey:
This is a solid performance. But the smaller number of people switching to AT&T to get access to the phone may mean:
We're aware that the current version of Google Mobile App does not fully support Apple OS 3.0. It is still functional, but some users may experience difficulties using voice search when lifting the phone to their ear (like you reported) or have blank rows appear in their search history. If you want to conduct a voice search, just tap the microphone icon instead of lifting the phone to your ear.
Apparently they're working on the fix.
Update: Apple put out a press release that says it sold more than 1 million 3Gs iPhones:
Apple today announced that it has sold over one million iPhone 3GS models through Sunday, June 21, the third day after its launch. In addition, six million customers have downloaded the new iPhone 3.0 software in the first five days since its release.
