Rivera looked through the IMAP packets leaving the device and saw that "Yahoo's IMAP server was not responding to the phone's requests to fetch new messages with the correct response," explains Cnet.
Therefore, instead of sending tiny commands, the servers were sending back blocks of data up to 25 time larger than necessary.
Adds Rivera:
This can also be read as: Your phone is downloading ~25 times as much data as it normally would, had you sided with another e-mail provider.
Although neither company has commented, Microsoft did say last week that only "a small (low single-digit) percentage" of WP7 owners were seeing the data leakage.
