Review: T-Mobile myTouch 4G
Browser
The browsing experience on the myTouch 4G is mostly the same as on any other Android phone, except for the fact that it is a hell of a lot faster when under HSPA+ coverage. The browser software does not appear to have been updated, and other than the substitution of T-Mobile's home page, you might not be able to tell it apart from other Android handsets. Still, that HSPA+ data connection is exciting when you have it. Web pages just pop onto the screen fully loaded.
You can use your finger to navigate around web pages directly on the screen or use the track pad on the front of the phone. There is a full list of settings that let you customize how the browser operates (such as enabling / disabling JavaScript, managing passwords and privacy).
Customize
The myTouch 4G is an HTC Android phone. That means you can change nearly everything. In fact, T-Mobile and HTC have made a pretty big deal about the myTouch series devices being yours to customize as you please. For example, when you first boot the phone, it asks you a bunch of questions about how you plan to use the phone (mostly to check email, mostly to upload photos, etc.) and it then creates a user profile on the fly during set up. That's pretty cool.
The myTouch 4G also offers a bunch of different themes and modes which were conceived from HTC's Sense UI. They can be customized at will, and the different profiles prioritize different applications depending on how you'll be using the device.
Obviously, with five home screens (expandable to 7 if you want!), Android widgets and shortcuts, the possibilities to personalize the phone are unlimited.
