Dear *****,
Thank you for your email. These options are not included in the Official HTC 2.1 Release for the Hero. The reasons for not including these are down to Google Android who develop the Applications and what devices and updates will include them. Thanks for contacting HTC. If you have any further questions, please do not hesitate to contact us again.
