TechSpot published Nokia Lumia 525
A quote from the article:
Nokia has been especially successful with their entry-level range of Windows Phones, particularly the Lumia 520, which on the back of its dirt-cheap price, quickly propelled itself to be the best-selling Windows Phone. A successor was always on the cards, but what Nokia has provided ? the Lumia 525 ? is a little unusual.Nokia Lumia 525 Review @ Techspot
In nearly every way, the Lumia 525 is the same as the Lumia 520: same Snapdragon S4 SoC, same five megapixel rear camera, same 4.0-inch WVGA display, same storage options and the same design. Nokia has bumped up the RAM from 512 MB to 1 GB, allowing you to run more apps in the background, as well as the latest games. The software included is also the latest and greatest, for what it's worth.
