To add to the above, wpcentral has a story from Business insider which reports
The head of a company that develops mobile apps is expecting a significant update to Windows Phone 7 in February. Among the changes: easing restrictions for third-party developers, which could increase the number of "long-tail" apps available for the phone.
We are already expecting an update in January which is supposed to bring copy and paste together with phones on the Verizon and Sprint networks so Iâ€™m not sure how this February update relates to the former. The next 60 days should be very exciting.
