I don't think Apple will use a bigger screen. When the original was in development, Apple did tons of research on ergonomics and usability. They decided that the size of the screen is perfect for hands. With iPhone you can touch anywhere on the screen without shifting your hands around. On the larger Android devices you need to juggle the phone around in your hand to reach corners. This might seem very little and is often overlooked but it plays a huge part on how the consumer interacts with the device.

BINGO!!!

Well, it has always been up to the developer what they support. So i don' know how that makes apple evil. Android has this problem. Im assuming your a "fandroid" by your post fatstar. You apple might introduce one degree of fragmentation, when android has hundreds of new ones per year.

I have tried a two different carriers, Orange/T-Mobile who are essentially two carriers in their own right but merged and use eachothers equipment... and now O2. I have also had a few replacement phones as well.

The thing is the others in my house use Orange/T-Mobile and they have great signal on their phones (not iPhone) and I have a works phone which is O2 and that also has great reception.

The issue appears to have been introduced since the 5.0.1 issue for some iPhone 4S and iPad 2 models, and a fix has already been released for the iPad 2 where they found the phone's signal software was crashing when switching between 2G and 3G. But the fix was not put in the latest iOS5 patch for the iPhone 4S.

My goodness, if you look at the Apple forums it appears to be quite widespread with people in random countries having the problem. It is defo a software issue, not hardware, because all of us noticed it happened after the battery update patch not long after launch.
:(

(PS. Props to the Apple support... no questions, they just swap the phone! Amazing. Although the first time they weren't giving me an unused phone, or atleast one wrapped in plastic around the box. I queried that and he happily went to get one that was, he didn't even argue that fact. Great stuff on that front)
