The Sony Xperia Ion was announced at the beginning of the year, but entering the halfway point of 2012 we still don't have a solid release date. Signs point to June, and a trip the halls of the FCC further suggests a release next month. AT&T LTE is here with support for the 700MHz and 1700MHz bands. 3G support is present for AT&T's standard 850MHz and 1900MHz bands, but a 1700MHz allotment is a bit of an anomaly.
