I can attest to occasionally experiencing this problem. It is rather intermittent for me and I can mostly control the problem by not moving the phone from my ear during the conversation.
This is a little frustrating. I get the antenna being affected by my hand but this proximity sensor problem is just bad engineering (either software or hardware).
My thoughts on my new iPhone 4. I just received it yesterday from FedEx (it was fun watching the FedEx package being tracked from China through Hong Kong through Anchorage through Indianapolis and then to Loveland, OH where it was routed to me). I received it one day ahead of Apple’s expected revised delivery date.
I say “revised” because AT&T and Apple screwed up and missed my first delivery date. The unit was supposed to ship on July 2 but they updated their date on July 3 to say that it was going to ship a week or so later. I was upset and I called Apple – the very polite and professional rep apologized but couldn’t change the ship date. He did give me a bumper as a consolation gift – good thing too as it turns out.
Apple has recently put out an open letter explaining that they have made a mistake in calculating the signal strength bars on their hit product, the iPhone (all versions up to the latest iPhone 4). I am glad that they Apple code developers have stumbled on this bug and are producing a fix. We all know that there are a few more software bugs in every product, so it is no surprise that Apple has a bug in this portion of their code.
But, is that really the fix? No.
All wireless devices need antennas. If you are as old as I am, there is a chance that your first mobile phone was a “bag phone” or a “car installed phone”. These phones were massive and required a car or, at least, a briefcase to carry them around. The towers were so far dispersed that you needed a BIG antenna that was putting out mega-wattage to reach them. Putting that antenna up to your head would almost certainly turn your brain to scrambled eggs in a couple of weeks or so. These monsters were also analog and all you could do was talk on them (no texting – how in the world did we survive?).
I just upgraded my iPhone 3G to the new OS today. I must admit that the new features (especially the ability to group apps together) is quite nice. I wish I could take advantage of the backgrounds but that doesn’t work for a 3G phone.
The biggest complaint on the entire process is that it took FOREVER to do the upgrade. It took over 4 hours to do the backups, reflash the ROMs, and then re-sync the apps, movies and songs back to my phone
My biggest advice to anyone that is going to do this upgrade soon – take your time. Plug it in, get it started, and then go do something else for several hours.
The FTC has released new guidelines for advertisers. One of those guidelines is that advertisers of diet products cannot have a famous (and formerly fat) person stand there and tell you that they lost 48 pounds in 48 days and you can to if you will just give them $480. Most people understand that they only thing that will lose weight in those schemes is your wallet. It is good for the FTC to demand a bit of realism there.
The FTC also says they will restrict bloggers from talking about products where they received the product or service as a gift in order to elicit the blogger’s review (favorable or unfavorable). There are some services out there that will help you get free products as long as you talk about them on your blog. I think these sites and services will be out of business soon.
