NEW YORK ( TheStreet) -- Despite the technical difficulties that plagued Apple ( AAPL - Get Report) partner AT&T ( T - Get Report) on the first couple days of new iPhone 4 pre-order sales, many analysts (and fanboys, of course) see the next-generation iPhone -- of which about 600,000 were sold on Tuesday -- as the smartphone to beat.

That being the case, AT&T, Verizon ( VZ - Get Report) and the rest of the telcos are quickly racking up Android partners to exploit the extremely capable Google ( GOOG - Get Report)-made OS that, according to The NPD Group, outsold Apple's iPhone OS in the first quarter to become the country's second best-selling OS ( Research in Motion ( RIMM) still ranks No. 1).

Next week, Motorola ( MOT) and Verizon will unveil the new Droid X Wednesday at a New York City press event, where tech execs from Adobe ( ADBE), Google and Motorola will take the stage presumably to wax about the many advantages of the Android OS.

Read on to see a collection of the newest, most highly-anticipated Android gadgets.

Motorola Droid X

Its unveiling falling on the day before the new iPhone 4 becomes generally available, the Motorola Droid X will feature a 4.4-inch display screen, making the device the second oversized touchscreen Android to hit the market (it follows the HTC EVO). Reviews by Engadget also reveal a Swype-capable keyboard. The Droid X, due out sometime in mid-summer, marks Motorola's second Droid wave -- and what the company most likely hopes helps its fading stance in the fast-moving smartphone market.

HTC Aria

As far as we know, AT&T still carries the exclusive for the Apple iPhone. However, AT&T has started to beef up its Android offerings and announced the HTC Aria earlier this week. With a 5-megapixel camera and running on Android 2.1, the Aria is smaller than a deck of cards, and will be available for $130 (after rebate) around June 20.

Sprint HTC EVO 4G

Only on the market for about a week from Sprint ( S - Get Report), the HTC EVO 4G saw new smartphone customers lining up outside city stores on its debut. The EVO, powered by a 1-gigahertz Qualcomm Snapdragon processor, is the first 4G phone and operates on a limited WiMax network as well as a 3G system.

HTC Droid Incredible

The HTC Droid Incredible has been a boon for Verizon, which recently reported that the Android smartphone is back-ordered until mid-July. The Incredible features a dual LED-flash 8-megapixel camera, a 3.7-inch touchscreen and the fast Snapdragon processor that's becoming the expected standard in new Android phones. The phone will upgrade to Android 2.2 sometime this summer.

Samsung Galaxy S

Another phone running Android 2.1, Samsung's Galaxy S made its debut in Sin City during the big CTIA Wireless conference. Like the EVO 4G, the Galaxy S -- with a width of less than a half-inch -- comes with a large 4-inch high-definition screen, underlining the current obsession with sharper smartphone images.

Dell Streak

Dell

Dell ( DELL) skipped debuting its first Android gadget in the U.S. and instead kicked things off in Europe, where its Mini -- known now as the Streak -- will hit U.K. shelves later this month. More of a mini-tablet/giant smartphone, the Streak, whose 5-inch screen is about an inch bigger than the EVO's, will sport a front-facing camera and a 5-megapixel camera on its back and includes HD video output.
