The thing is, I have used all sorts of cell phones and I have never experienced this. Yes in today's market the blackberry 9300 would be a "middle of the road" device. But I have used far older devices and they have all downloaded files off the internet at a constant rate albeit a bit slower due to lack of 3G support.
I have asked people who own Blackberrys like the 8250 and the Bold 9700. They are different networks and all experience this periodic pause in their downloads.
They shrugged it off as saying it's normal.
Yet I have experience in networking and cell phones to know this is not normal.
It seems to only be limited to blackberrys as my Sony Ericsson downloads the exact same file just fine and it's got a weaker processor and less RAM.
Does this make sense?
