The FT’s personal technology expert answers readers’ queries

Q. We are considering acquiring new smartphones. How would you rate the HTC TyTn II against Motorola Q9? (I understand the Vodafone V1615 is the same as the HTC TyTn II with just a badge change. Is this true?)

Our criteria for the new handset include the following: a) 3G; b) Microsoft Windows Mobile 6.0; c) is Push e-mail compliant; d) Bluetooth for use in cars; e) long battery life; f) reasonable weight and pocket size; g) reasonable screen size for reviewing e-mails etc. Camera, Wi-Fi, MP3 etc are useful but not essential.
