We round up the review of hottest cell phones and most recent Must-Have cell phones in this summer. And we round up the objective reviews by editors of cnet.com. The following gadgets are presented in alphabetical order.
Review of iPhone 3GS - 32GB

The good: The iPhone 3GS finally adds common cell phone features like multimedia messaging, video recording, and voice dialing. It runs faster; its promised battery life is longer; and the multimedia quality continues to shine.
The bad: The iPhone 3GS' call quality shows no improvements and the 3G signal reception remains uneven. We still don't get Flash Lite, USB transfer and storage, or multitasking.
The bottom line: The iPhone 3GS doesn't make the same grand leap that the iPhone 3G made from the first-generation model, but the latest Apple handset is still a compelling upgrade for some users. The iPhone 3GS is faster and we appreciate the new features and extended battery life, but call quality and 3G reception still need improvement.
Specifications: OS provided: Apple Mac OS X 10.4.11 ; Talk time: Up to 600 min
Price range: $299
Review of HTC Touch Pro2

The good: The HTC Touch Pro2 features a sharp, spacious touch screen and an easy-to-use full QWERTY keyboard. The Windows Mobile smartphone also includes conference call management tools for business users and offers good call quality. It also has Wi-Fi, Bluetooth, and GPS.
The bad: The smartphone is heavy and bulky. No U.S. 3G support on this version and it's expensive. Onboard memory is low, and we would have liked an upgraded camera.
The bottom line: With a feature set to match its large size, the HTC Touch Pro2 will be a great device for power and business users once it finally hits North America and adds U.S. 3G support.
Specifications: Band/mode: W-CDMA 900/2100 / GSM 850/900/1800/1900 ; OS provided: Microsoft Windows Mobile 6.1 Professional ; Talk time: Up to 510 min

Review of LG enV Touch
The good: The LG enV Touch has two beautiful displays, a nice touch-screen interface, and a great QWERTY keyboard. It has impressive features, such as a 3.2-megapixel camera, EV-DO Rev. A, and a full HTML Web browser.
The bad: The LG enV Touch's touch-screen interface could use some refinement, and the Web browser experience is not as smooth as we would like. Visual Voice Mail and corporate e-mail support costs additional monthly fees. The lack of Wi-Fi is disappointing.
The bottom line: The LG enV Touch's combination of great design and top-notch features makes it one of the top Verizon Wireless Wireless phones we've ever seen.
Specifications: Band / mode: CDMA2000 1X 1900/800 ; Talk time: Up to 260 min ; Combined with: With digital camera / digital player ;
Price range: $99.99 - $599.99
Review of Palm Pre

The good: The Palm Pre's multitasking capabilities and notifications system are unparalleled. The smartphone features a vibrant display with multitouch functionality as well as a solid Web browser and good multimedia integration. The Pre offered good call quality and wireless options include 3G, Wi-Fi, Bluetooth, and GPS.
The bad: The Pre's keyboard is cramped. Battery life drains quickly and the smartphone can be sluggish at times. Lacks expansion slot, video-recording capabilities, onscreen keyboard, and Flash support. The Pre App Catalog is still in beta with a limited number of titles.
The bottom line: Despite some missing features and performance issues that make it less than ideal for on-the-go professionals, the Palm Pre offers gadget lovers and consumers well-integrated features and unparalled multitasking capabilities. The hardware could be better, but more importantly, Palm has developed a solid OS that not only rivals the competition but also sets a new standard in the way smartphones handle tasks and manage information.

Price range: $199.99
Review of BlackBerry Tour 9630
The good: The RIM BlackBerry Tour 9630 offers world-roaming capabilities as well as Bluetooth, GPS, and a 3.2-megapixel camera. The smartphone offers a great design that combines a sharp display and an easy-to-use QWERTY keyboard in a fairly compact size.
The bad: The smartphone lacks Wi-Fi. The Web browser falls short of the competition, and there's a bit of shutter lag on the camera. You can't save applications to a media card.
The bottom line: With a winning design and fast performance, the RIM BlackBerry Tour 9630 is one of Verizon Wireless' top smartphones for both business users and messaging fanatics.
