OK, I've worked in IT long enough to know a few things about multi-tasking. I've also owned enough PDA's to know, that only more recently have they been able to cope with doing more than one things at once. Also, if technology is badly coded at managing 2 things at once, the overhead hit can go through the roof.
OK, so if I read between the lines of the many different issues with the Iphone, some seem far more effected than others. However, a pattern may be emerging. The different groups, that worked on each of the Iphone 3G's core functions would have been told what technology gets priority and when. If one of those functions has a little too much priority, the other function may think the device has locked or may itself lock (look frozen) or instead of taking twice as long, take 5 times as long.
My years of doing benchmarks with multitudes of computer systems (single and multiprocessor), what I'm reading here, in effects looks a lot like thrashing.
Just read a post from a guy who sayings synching is "SO SLOW". I'd like him to try turning off the phone itself, the 3G, the edge - effectively turn it into an Itouch (my Itouch (upgraded), synching is very fast !!
Indeed, thrashing may explain the heavy reduced battery life where people see the Iphone 3G switching constantly to edge and 3G. Again a simple firmware fix to say (Don't search for 15 secs after 1st switch my help a lot).
Just an observation, as I say, I've benchmarked for years and this device looks like it's struggling when it has to deal with more than one thing at once (I've noticed my Itouch throws fits when I run some of the external apps (music can skip whilst playing !!).
On EDIT - My itouch, sexy scrolling in Safari "skips" (grey blocks before refresh) too if anything else is now running. The upgrade definitely did something to slow it down so there wasnt' a lot of free CPU.
