Google made no new-generation Nexus announcements at its I/O 2013 conference, but at least the Motorola XFon is apparently headed to major U.S. carriers.

Earlier there were rumors that Google had ditched the XFon for not being innovative enough, but new reports now suggest the handset may be heading to Verizon Wireless later this year. FCC documents, meanwhile, show an XFon model for Sprint as well.

News of the Motorola XFon hitting Verizon Wireless and Sprint follow previous FCC filings for the Motorola XT1058 for AT&T. According to the folks over at Droid Life, an .ini file pulled from leaked Motorola USB drivers shows that the XT1058 will be accompanied by an XT1060 model, which seems to be a variant of the XFon with CDMA radios for Verizon.

The .ini file reportedly lists out model numbers for devices picked up when using Motorola;s RSD lite application. The XT1060 model has a chipset labeled "MSM8960CDMA," which is a Snapdragon 4 Pro dual-core version similar to the one leaked in benchmarks for the XT1058. This may be the Pro chipset clocked at 1.7GHz with Adreno 320 GPU, not the version with Adreno 225 GPU.

Meanwhile, an XT1056 model also passed through the FCC with the LTE band 25 for Sprint's network. The handset also features NFC and HSPA+ 21, and many believe it's the Sprint-bound version of the XFon.

All things considered, the Motorola XFon may not be unlocked, but instead sport different versions designed for specific networks. Many believed the XFon would be an awesome unlocked smartphone with a low price tag like the Nexus 4 and also capable of connecting to CDMA networks such as Sprint and Verizon Wireless.

Rumors of a Google X Phone / Motorola X Phone have been making rounds for quite a while, but nothing materialized yet. Various rumors suggest all sorts of things and it's difficult to tell at this point what's real and what's not. Motorola has made no official announcement yet, so nothing is official for now.

On the other hand, one thing's for sure: Motorola has something up its sleeve, and at least one device is bound to hit the market soon.
