I don't know about you, but after doing the 2.0.2 update, my first generation iPhone has been receiving less signal and the OS has been slower. I now find myself unable to even make a call more often than the 1.o software or even the 2.0.1 software. Up until now software updates have been uneventful, as they should be. I think a good sign of a software update is not knowing that you did it, or in the case of major bug fixes, greater performance.
When I connected my phone after TDL Live two weeks ago (when the new software became available) iTunes didn't even recognize new software was available until I clicked to have it check. Ever since the update, tapping on the keyboard has resulted in delayed text input, Apple native applications "unexpectedly quit", and the phone more often downgrades connectivity to the slower GPRS network (indicated by the circle inside a square icon). Prior to the upgrade, my phone connected to the GPRS network only once.
This brings us back to a topic from TDL Live . . . Is Apple just too thinned out? We saw the hack job MobileMe release which by my accounts still isn't resolved. Apple has been expected to debut game changing products, and the street is continuing this expectation each quarter. If Apple hadn't released the 3G iPhone when they did, the stock would have taken a substantial tumble. I hope a corrective update is released to fix the 2.0.2 fix or I'll be reverting back to 2.0.1.
