I just looked on the back of the box for my company Blackberry 8800 and it mentioned "EDGE Class 10 for fast data transfer". I wonder what the different classes mean in terms of speed? Wonder what class our iPhones have.

The class is basically how fast it works, it deals with how many "slots" the data connection uses. Apple's tech spec page doesn't list the class for EDGE (class 10 is the fastest). I can't find anything that specifically states it, but based on data speeds I've seen it has to be a class 10 device.

I actually wonder if the iPhone is the same class as the blackberry. My Blackberry is much faster on Edge than the iPhone - there's no comparison really.

The iPhone chip is Class 12. That means _up to_ four slots for download and four for upload... with a maximum of five slots at any one time. So it's divided 3+2 or 4+1, etc.

Or on a full cell, you might only get 1+1 :)

Each slot is worth 59.2kbps.

So if you got lucky and you were given all four download slots for a particular request, you could get the maximum 4 x 59.2 = 236.8 kbps down.

Well, if it's Class 10, that's still a max of four down or two up, with max total of five at a time.

So it can download just as fast (4+1) as the iPhone. It just can't max out as much going upstream (which only happens if you're uploading a file).

I didn't realize there was a class 12, but I looked it up and you are right. Where did you find the iPhone was class 12? I looked through Apple documentation and didn't find any mention of it.

The iPhone chip is Class 12. That means _up to_ four slots for download and four for upload... with a maximum of five slots at any one time. So it's divided 3+2 or 4+1, etc.
