The Lumia 1525 from Microsoft was leaked only yesterday by @evleaks, but the notorious leakster isn't finished with this rumored handset. Today, it's reported that not only will the Windows Phone be available through T-Mobile US, but it won't be carrier exclusive meaning consumers on both AT&T and Verizon may be able to get their hands on the device – as well as those who reside outside the US.
Since it'll be available alongside the Lumia 1520 in places, the Lumia 1525 is said to have some notable upgrades over its sibling, including the new Snapdragon 801 SoC (system on a chip).
The current Lumia 1520 utilizes the snapdragon 800, making this unannounced handset a worthy upgrade should reports showing differences between the SoC versions be anything to go by. The 801 includes support for DSDA (Dual SIM Dual Active) and eMMC 5.0 (for faster access to internal storage), while in some models improving CPU, GPU, ISP (image signal processor) and memory interface speeds.
Unfortunately, there's little else to go on, but we could be seeing early signs of some upgraded hardware. While we're filing this under rumor, anything is possible.
