I have a query.

When downloading a file from The App World or email attachment, I have noticed that the download rate is intermittent.

There are bursts of speed and then a wait of about a second or 2 where there is the waiting clock symbol and then the download continues.

Is this because of the buffer being filled up or is it based on the network.
I have noticed this occurs on both 2G and 3G networks.

Any help would be helpful
