The Blackberry 7230 was launched in U.S and Australia. It gives the user a colour screen, always on e-mail and internet browser. eWeek published a review of this device connected to the T-Mobile network.
"... the 7230 maintains the mobile messaging competency on which RIM's BlackBerry devices have risen to popularity. However, users who need more than basic messaging and cell phone functionality will have to look elsewhere.
The 7230 does include applications for managing contacts, calendars, to-do items and notes, but it lacks appreciable third-party application support and is also missing any sort of memory or peripheral expansion slot. Competing Pocket PC- and Palm OS-based devices offer these things."
