Phone Features
The T-Mobile G1’s vibrant, high-quality screen slides open to reveal a full QWERTY keyboard, great for communicating with friends online or using the phone’s email, IM and mobile messaging capabilities. As another option for accessing the device, the T-Mobile G1 comes equipped with a convenient trackball for more precise, one-handed navigation. The 3.2-inch touchscreen has a 320 x 480-pixel resolution and a 65K color depth. The T-Mobile G1’s touchscreen interface is unique, providing you with a more customizable, interactive touch experience. For example, you can set a signature gesture to unlock the screen (there are 30 million possible combinations). There are also different taps for different types of commands–for example, you can use a short touch to launch an application, or a long press on any screen will give you additional options, similar to that of a right click on a mouse.

The phone has an internal 192 MB RAM/256 MB ROM memory, and it’s expandable via optional MicroSD memory cards up to 8 GB in size (a 1 GB MicroSD card comes with the phone).

The hinged screen slides open to reveal keypad and closes to prevent accidental dialing.

With one-click contextual search, you can search for relevant information in a flash with a touch of a finger. A full HTML Web browser allows users to see any Web page the way it was designed to be seen, and then easily zoom in to expand any section by simply tapping on the screen. Built-in support for YouTube allows you to enjoy YouTube’s originally-created content, easily navigate through YouTube’s familiar video browsing categories or search for specific videos.

With Google Maps, Google’s groundbreaking maps service, you can instantly view maps and satellite imagery, as well as find local business and get driving directions, all from the phone’s easy-to-use touch interface. The T-Mobile G1 also includes Google Maps Street View, enabling you to explore cities at street-level virtually while on the go. Without taking a step, you can tour a far-away place as if they were there–standing on the street corner. Even better, the Google Maps feature syncs with a built-in compass on the phone–an industry first–to allow you to view locations and navigate 360 degrees by simply moving the phone with your hand.

Use the G1’s 3G and Wi-Fi connection to attach and share pictures over email and MMS or download music from your favorite web sites, as well as upload and post pictures to your personal blog.

The G1 features a rich HTML email client, which seamlessly syncs your email, calendar and contacts from Gmail as well as most other POP3 or IMAP email services. The Gmail application provides features such as conversation view, spam filtering, search, and labels that Gmail users enjoy on their computer while offering new features such as integration with the phone’s contact list. And it multitasks, so you can read a Web page while also downloading your email in the background.

It also combines Instant Messaging support for Google Talk, as well as AOL, Yahoo! Messenger and Windows Live Messenger in the U.S., and IM presence allows you to see whether your friends are online, offline, away. The G1 also supports advanced text messaging features, enabling you to easily flag, delete or move groups of messages and keep track of group conversations through threaded text messaging. The Google Calendar app on the G1 syncs with the Web-based version, so any event that you add to your phone will show up on the Web-based Google Calendar (and vice versa).

Frequently Asked Questions
Q: Do you have to have a Google account to use T-Mobile G1?
A: Yes, customers must log into the phone using a Google account login when they first use the device. Once you do log into T-Mobile G1 using a Google account, your Gmail and Google Calendar will all sync to your phone providing secure, up-to-date access to your personal information. If you don’t already have an account, the startup process will walk you through creating one. Creating a Google account is free.

Q: Do customers need a voice and/or data plan to use T-Mobile G1?
A: Yes, when you purchase T-Mobile G1, you must add one of two T-Mobile G1-specific data plans to their account. This is similar to other all-in-one devices we offer like the T-Mobile Sidekick or the T-Mobile Shadow. Customers must also have a voice plan.

Q: Is the G1 compatible with your HotSpot @Home service?
A: No. Unlimited HotSpot Calling (formerly named T-Mobile HotSpot @Home) is not included in the T-Mobile G1, although the device can browse the Web over high-speed wireless connections including Wi-Fi and our 3G network.

Q: Are there any advantages to using Gmail on the device versus another type of personal (POP3 or IMAP) account?
A: Yes. After first logging into their Google account, you will have all your Gmail, Google Contacts, Calendar and Talk data automatically synchronize with the phone. Anything you do on the phone with these products will seconds later become available on the computer and vice versa. If you were to ever lose their phone, their information will still be available and seamlessly synchronize with a replacement G1. You will also benefit from push email and calendar alerts (this is also available for the multi-headed email client). Finally, Gmail’s contacts are synchronized automatically with the phone’s contact list.
