I read where Yahoo is sending back 25 times more data than it should to Windows Phone 7 users. I wonder if the same is happening to webOS users? It has something to do with the way Yahoo is responding to IMAP requests.

I ask because I use Yahoo mail on my Palm and I'm wondering if the same is happening thus causing more battery usage, etc.
