The Lumia 730 has just swung by the FCC. We know quite a bit about the Lumia 730 so far. It's internally known as "Superman" and is the successor to the Lumia 720. It'll have a 4.7-inch display with a possible 720p screen. You can also look forward to 1GB of RAM, dual-SIM support, and more.

The Lumia 730 (RM-1040) did the usual FCC dance. In the documents we confirm a few things we knew about the Lumia 730. Confirmed? Dual-SIM and microSD card support. Here are the rest of the specs we've learned from sources. Plus it looks like this device will have a removable battery.
