For the 10.5 hours with the E71 - I saw it from GSMarena.com's listing: http://www.gsmarena.com/nokia_e71-2425.php
as well as it's review of the E71:

As for the Blackberry Bold being 4-5 hours:
GSMarena.com's Listing shows 5 hours:

As well as a picture at the Rogers Cup in Canada where Rogers actually had the phone on display.
Standby: 15 days
Music: 17 hours
Talk: 4 hours

Now what I do not know is which time is "3G" talk time and which one is "GSM" talk time. I naturally assume that the GSM talk time on the Bold will increase, but the listed talk time for the E71 - would that increase, even after turning off 3G?
I'm sure I'll found out more answers as time goes on.
