I looked at the new MS Surface today and the sales guy had pretty good knowledge of the tablet market
plus he had worked for APPLE sales before
he knew how BB phone and PB work together, he wants to see BB10 suceed,
so I picked his brain of how to install like Yahoo native email, as yahoo uses a POP email account and once you have downloaded your email from either your desktop you cant see it anymore on the PBand vice verse
if you need your email on both you have to use an IMAP email, like gmail.com, or the new outlook.com,, this way the email stays on the server
Yahoo email is not a IMAP, rather on old fashioned POP email
