The new T-Mobile Samsung Galaxy S II “4G” Android smartphone is $279 if purchased at a T-Mobile store or at the carrier’s web site, though you do get a $50 mail-in rebate which brings the final price to $229.  However, you can skip the mail-in rebate and still save $50 by purchasing from Wirefly.

Wirefly has the T-Mobile Galaxy S II for $179 when you sign up for a new account and agree to a two-year service commitment.  If you’re already a T-Mobile subscriber and are eligible for an upgrade, the price increases by $20 to $179, no mail-in rebate required.

Update: LetsTalk.com has the phone for $149 with a new account.

Microsoft is prepping for the second wave of Windows Phone handsets – and so are U.S. carriers.  AT&T is among the first to show off Windows Phone 7.5 phones, including the HTC Titan and Samsung Focus S.

Neither of the phones have been given pricing or release date details – at least not publically – but we know a great deal about each of them aside from these admittedly important details.  Each features a fast processor, a large screen, and the latest version of the Windows Phone OS, in addition to the usual array of wireless tech.  Both are also HSPA+ ready, too, so you’ll get faster download speeds than standard 3G models.

One interesting detail: the Samsung Focus S, like its predecessor, will include a microSDHC memory card slot for additional storage.  Microsoft’s other smartphone offerings, like Apple’s, lack memory expansion.  Here’s hoping they’ve solved some of the issues that have plagued the 2010 Samsung Focus.

While it may sound like a character from an upcoming Transformers movie, the Nexus Prime – apparently to be sold as the Galaxy Nexus – is set to be the first smartphone running the next version of the Android OS, code-named Ice Cream Sandwich, and the new Android flagship phone.  It will be announced late this evening (U.S. time) in Hong Kong.

Like the other Nexus-series handsets, the Galaxy Nexus from Samsung will be a pure-Android experience without third-party overlays, UI tweaks, or carrier tampering. 

In addition to Android OS 4.0, the 4.7-ounce Nexus Prime / Galaxy Nexus is expected to feature a dual-core 1.2GHz TI OMAP4460 CPU, a 4.6-inch AMOLED 720p HD touchscreen display with curved glass and a high DPI, 1GB of RAM, either 16 or 32GB of onboard storage, Bluetooth 3.0, an 8MP camera with 1080p video capture, a front-facing camera, and a PowerVR SGX 540 GPU.  LTE is also widely expected to be part of the wireless array, and NFC technology for Google Wallet is also thought to be included.

The Nexus Galaxy is believed to be headed to Verizon Wireless in November.
